crespiI've had my sgs3 for about 3 months now and as soon as I got it I rooted it like I do all my androids. I've been runing cyanogenmod 10 for almost the whole time i've owned it and I can tell you one thing, there is nothing better than a fully rooted droid running cm10. All the complaints about battery life, customization, all that stuff is irrelevant when you have 100% control over your phones hardware.
AOKP and AOSP give a lot more customization options than CM10 imo. The mashups are the best though, handpicked features from all 3 popular developers
