When my wife went to get her new phone and i had an upgrade ready, the verizon rep talked me into the charge, i just returned it for the bionic yesterday, i was holding out to see the galaxy nexus, but ended up getting the bionic because it was $200 cheaper for me, and will get ICS eventually. and to be honest, the nexus didn't really impress, it reminded me to much of the charge, and just didnt have a solid feel to it. (and when the back cover snapped off and the battery fell out as soon as i picked it up, and the rep said i was the first to look at it, that didn't inspire confidence)
The charge also lost all data near once a day, and i live in an area where 4g is available, my wife's rezound has not dropped it once, and at least as long as i have had the bionic it hasn't either. Battery life, they seem about the same really. Contacts on the bionic are handled MUCH better then on the rezound or the charge, as in you actual can have some quick icons on a home page, as a widget that groups them, and not just a bunch of individual widgets one for each.
And, even compared to my wife's rezound the call quality on the bionic is the best of the 3 phones mentioned here. The charge had lots of feedback
The bionic is superior to the charge in every way, even screen, in the store the screens brightness is turned down, and the charge screen looks better, but you turn them both up, then you can see that the on screen text and icons on the bionic are sharper then the charge, i think the charge has a lower res so everything is a bit bigger and easier to read, that is what makes the charge appear to have a better display, when you look close though you can see the difference. the other thing that makes the charge appear better (at least from someone who came from a droid x) is that it is colorful, motorola doesn't exactly make a colorful interface. and you have no idea how much i would love to change it
But that being said, there is one thing that my wife's rezound and the charge i had for near 2 weeks have that the bionic does not, on my droid x i always got a process.gapps has force closed, and i have not see that at all on the charge or the rezound in 2 weeks of heavy use, but i got my bionic yesterday and have seen it already 3 times, seems to be linked to my gmail app, but i have the sync on it turned as low as it will go, and only for inbox, still get it even after clearing all the app data. A buddy has a droid 3 that also gets this, so my guess is, it might have something to do with moto.
