FWIW: The Tranquil 4.2 ROM has been excellent so far. I have been using it constantly for 3 days and I haven't had any issues. It is my understanding that their only known issue is with Zoe (whereas I understand Newt's ROM has Zoe working, if that matters to you...but trolling through that thread's posts on XDA, it sounds like VZW data may be not 100% -- which is more important to me). Also, it sounds like they are working on upgrading this one to 4.2.2 (which, again, I think Newt is already on).
I'd like to see them now wait until the VZW code is posted, as they're finally releasing the One this week (and that's where they've been porting the code from)...would likely make for a more stable ROM, especially WRT the radio stuff.
