Both of the roms I have tried seem great, but on CyanCore, I get ANRs on Maps, Google Play, YouTube won't open, and sometimes will slow down so far that I have to force shut down. Google Now works great though (except for directions). When I tried JellyCore, both cameras work great, Maps, Google Play, Navigation, and YouTube all work well; but Google Now does not work. (After tapping on mic, gets stuck on initializing). I know this is still in the early stages of development, but please add this to your "Known Bugs" list for others who wish to flash these roms. Facebook and Twitter force close on sign in on both roms.
I have been able to run Twitter and Facebook on all builds. I use Twitter all the time to update what I am up to. Youtube runs fine, there are few restarts and I did list that. I really haven't messed with Google Now very much. I will post more known bugs if need be. I have been super busy lately with stuff going on at home.
