My favorite ROM so far is the JDroid Exodized ROM for your rooted HTC One X. I think this is the best ROM right now for the HTC One X.
The JDroid Exodized ROM gives you a fuller Google ICS experience with most of the Sense stuff removed while keeping the good things like the Sense camera UI so you can keep your continuous shooting mode. Performance and battery life are pretty good too so you can’t go wrong with this ROM.
I will continue to test more ROMs but in the meanwhile, I have to say this is the best ROM for your rooted HTC One X. Try
