I traded in my GNex with Jellybean for my S3. The Nexus was nice and smooth with JB, but the battery still drained too fast, the voice quality was crappy and the camera was as bad as any I've owned since the Og Droid.
The S3 has maintained rock-ribbed signal quality, voice quality is as good as I've ever seen, it clings to Wifi like a barnacle to a hull, the camera is excellent (though it oddly showed streaks around lighting the first time I used it, not since), and where GNex JB had a bit of hesitation when you opened the app drawer, there isn't a hint of lag on S3 that I've been able to induce. Mine is rooted, but I haven't seen a ROM worth flashing yet. THAT aggravates me. We, the Verizon faithful, sure got the poopy end of the stick on this one. This is the first time I've ever seriously questioned my loyalty to Big Red.
