Stick to dirty rom... XsMagical is going to update it to 4.2 once he gets it compiled.. He's got different phones he's doing it for as well, dude is good with his roms. I went to JellyBam and its the only other AoSP rom that is super stable
The CM 10.1 build from 1/13 works pretty good if you can live without a camera or GPS. My BT even works for the first time with AOSP and my Camry since 3/18 nightly on my gnex. Heavy development still ongoing to get the Camera working, and fix some bugs, but it is likely going to be "first" to 4.2.
