I've spent probably around 30 or 36 hours watching video reviews and reading forum posts, reviews, and spec sheets regarding the RAZR, RAZR Maxx, Rezound, and Galaxy Nexus over the last two weeks, and spent some time in a store playing with all four last night. (Well, in truth, the RAZR got about ten seconds of attention. It feels all wrong in my hand; as other than the battery, the two phones are identical, you can read RAZR Maxx when I write RAZR henceforth) I respect the Rezound love expressed in this post -- it's a great phone, and I can't make my mind up -- but I really don't think it's as simple as the folks who are saying that the Rezound is a superior phone with an inferior battery are saying.
ICS on the Galaxy Nexus was cool, but not a selling point, given that all the rest will be getting the OS soon enough. The real problem with the GN for me is the radio. Tests indicate that the GN has a much harder time finding and holding a signal, which had a negative effect on battery life, in addition to the obvious fury induced by dropped calls & connections. Although I travel into 4G areas weekly, I live in the Outer Banks of NC (we get 4G in March), and the local (non-corporate) Verizon store has had EVERY SINGLE Galaxy Nexus that they've sold returned for this very reason. So that one's out, and I'm going to ignore it from now on. The same review stated that the RAZR received signal more strongly than the Rezound (note, this was based only on "bars" displayed), though there were no apparent effects on data rates or call quality.
I'd have to give Rezound lovers the screen. The Rezound's 720p resolution, for me, trumps the S-AMOLED brightness of the RAZR/RAZR Maxx. That said, I don't think that would be the case for most people. One reviewer said that if you pulled both phones out in a dark room, it would be the RAZR that drew the crowd, and I suspect that's true. Most people seem to respond to those vivid colors; I don't so much, and that's why I was sticking with JVC projection TVs when everyone was buying LCDs. The screens are the same size, at 4.3"; this is interesting to me, because the footprint of the RAZR gives the impression of a bigger screen. This is of course due to the larger bezel, which is among the RAZR's biggest flaws for me.
The sound...well, I believe the Rezound uses a Wolfson (i.e., first-class) opamp for sound reproduction, and I can't find any indication anywhere of what kind of op-amp the RAZR uses. Edge to Rezound. Beats, however, should be ignored. All it is is an EQ profile, which you could reproduce with any app providing a 10-band EQ. And it CERTAINLY doesn't reflect "the way your music was meant to be heard," as Dre would have you believe. The headphones are certainly a nice perk, but are enormously overpriced at retail; you can get superior ones for $40-50 (I'm a headphone hobbyist, and Beats, particularly these iBeats, are generally not loved in the hobby. I have myself have three sets that are superior.). I actually preferred the RAZR's music app to the Rezound's from an interface standpoint. Also, the RAZR has integrated streaming of music from your home PC (or the cloud, presumably), and does not require a 3rd-party app for the purpose.
The Rezound's lack of an HDMI port is kind of a big deal; I carry enough damn adapters and dongles with me, and the previously noted issue with charging while it's connected needs no further discussion.
The RAZR's Webtop capability is awesome; an earlier commenter noted how awesome that feature is for a business traveler, and I wholeheartedly agree. This may well be the single feature (other than battery life) that's most militating toward the RAZR Maxx for me. Additionally, the RAZR features DLNA streaming; I could potentially stream HD Netflix to my Viera-capable plasma TV at home, without even plugging the phone in...how cool is that?! (I'm not sure streaming Netflix would work, of course, but I love the idea!)
The Rezound has Bluetooth 3.0, while the RAZR is stuck on 2.1. I'm not sure that really matters, especially as the Rezound does not support HID (i.e., mouse) profiles.
The RAZR has integrated "government-grade" security and an integrated Citrix receiver. These are potentially big deals for a road warrior; though in my case, my company wouldn't support it, no matter how much it would help them. The same integrated app that streams music to the RAZR also lets you access your home or office PC remotely. These capabilities are not even approached by the Rezound.
Generally speaking, the Rezound's camera is preferred by reviewers, but this is by no means a universal preference. In the admittedly limited environment of the Verizon store, I slightly preferred the pictures the RAZR took. Also, the slow-mo 1080p video capability is something the RAZR can't match right now. The front cam is also somewhat better on the Rezound.
With its water-repellent finish, Kevlar back and Gorilla-glass screen, I suspect the RAZR will prove more durable.
Most tech people I talk to say the 1.2 gHz TI OMAPS4 processor in the RAZR is superior (and faster) to the 1.5 gHz Snapdragon in the Rezound. In playing with the phones, I noted a very, very slight choppiness in changing between homescreens on the Rezound, but none on the RAZR.
The non-replaceable battery of the RAZR, of course, is a big handicap. However, in the case of the MAXX, it nearly doubles the capacity of the Rezound. For some, that will be a wash. But the RAZR Maxx gets my vote, since its battery will at least last much longer (particularly with the Smart Actions set properly; I checked the app out, and it's enormously flexible and cool.)
Both phones lack NFS, which is disappointing.
My current phone is an Incredible; which I've loved, but it's definitely aging. I've reached the point where I get the low memory warning every two weeks or so. I clear out my cached data, delete text threads, and find another app to delete each time, but the problem is never solved, and the thought of a factory reset after all the tweaking I've done makes my stomach churn. It's time for an upgrade! I've enjoyed Sense a great deal; the rest of my family have Samsungs, and they always seem to have more trouble finding what they want on their phones than I do. That said, I didn't mind Moto's new non-Blur overlay at all. In some small ways, I preferred it to Sense. One example: on the All Apps list, Sense has one giant screen that you scroll vertically through; non-Blur has several screens that you flip through horizontally. I found it to require less thumb motion to get down to YouTube at the end of the list, and the set position of app icons allows for easier mnemonics when it comes to locating an app.
As I said before, the RAZR's form is thin and pretty, but felt entirely wrong in my hand; it was all edges. The Rezound, by contrast felt great in the hand, although it was a bit too heavy. The weight will be more of an issue for me when the phone is in my pocket, particularly in the summer, when I'm wearing shorts rather than jeans or slacks. The Rezound's thickness is a looks-and-pocket-bulge issue only. The RAZR Maxx split the difference, for me: it felt quite good in the hand, and was just the right weight.
And for my money, the Rezound just doesn't look special enough. Both the RAZRs look sexy, and shallow as it may be to consider, will be getting second glances in airports and offices for a few months to come, while the Rezound just looks like a phone. It has a few nice touches -- the red grille and soft buttons and possibly the dark chrome-look bezel -- but they don't really come together to provide any particular look to me. My consistent reaction to it is, "meh." And I suspect that this is the biggest reason that the Rezound tends to lose out in most comparisons to the Galaxy Nexus and RAZR.
Then there's price: today, I've seen the RAZR Maxx for $229 with 2-year renewal, while the Rezound (which apparently is not selling well) is as low as $99. My head tells me to go with the Rezound, as I think it's a better bargain, even giving its missing capabilities. And those earphones would make a great present for my nephew. But lust is pushing me toward the RAZR Maxx, and the battery is reinforcing that with a bit of practicality.
