Rom/kernel recommendation threads are forbidden here because:-
A) No two people will have the same experience of a rom or kernel due to the vast differences in phone usage & setup which influence this experience (I.E how you use your phone & have it setup will influence performance/battery life/etc far more than a given rom or kernel).
B) Being XDA, if you're here, it's assumed you like messing with your phone. You're expected to make a nandroid, read some rom/kernel threads, and try some out for yourself to see how they work for you.
Mods will be closing this thread presently.
