I've tried about 3 different ROMs total on my Nexus and all performed well. There are some differences that led me to the ROM I'm favoring now, but by no means are there any "bad" ROMs on the Nexus. You can do what I do, if it works for you of course, is keep a nandroid backup of each ROM and you can switch it up every week if you get bored or something.I'm curious.. What ROM's do you find perform best in terms of "smoothness"/Stability/Battery-Life? I have been using GummyNex for a while (since 0.9.x) and just updated to 1.2.5 a few days ago and while my browser no longer force-closes constantly (knocks on wood), the battery is much worse! I just love the ROM's layout/feel/everything, so it's really hard to change!
Anyway, I would be very interested in your opinion!!
Thanks!
