On my Nexus, I get great 4G speeds here in the Atlanta market of 25-27 down and 11-13 up. Based on your results there must be an issue with your phone.
His results are not uncommon, from a comparison standpoint. I've been itching for a switch to the GN since launch. I ignore dbm's because the numbers are apples and oranges. GN's dbm's show actual 4g strength. Rezound and all other LTE phones show 3G strength. Those numbers don't mean anything for comparisons here.
However, when I run speed tests on the two phones, the Rezound wins most of the time. I tried in multiple locations. I noticed the same on Wifi as well. I've seen a couple reviews online that also had similar results. I love the look and feel of the GN and ICS, so I keep trying to talk myself past this - to rationalize the switch, but the results are what they are. Odds are, if you're getting 25-27/11-13, a nearby Rezound can get higher.
The only thing I'm telling myself now is, when you can pull down fast speeds like that, does it really matter anymore? In the end, for me, I guess I'm just feeling better knowing I've currently got the faster phone right now, in the Rezound. Just waiting on some custom ROMS now that it's unlocked, but in the meantime, I've still got that GN itch..
