Don't know which ROM to choose. Help

I'm getting my S3 tomorrow and im planning to get away from stock as soon as possible.

I would like a aosp or aokp based rom with good battery life, good music quality and good camera.

Im moving from a iPhone 4S and the music quality on that thing is amazing so i'm looking for something similar, but I hate the Samsung interface as i've played with my friends.

Does anyone have any recommendations, battery life is very important.

Thanks in advance guys

I like the look of the SuperNexus Rom but apparently the battery life is pretty bad
