Default Is there any rom that is head/shoulders above?

Hey guys,

Haven't used my old Kindle Fire for a while. I think I upgraded it to 4.2 a while back and that was it. Going on a trip this weekend, and was wondering if any roms seemed to work better than any other? There used to be problems with power management and the like, and well..I'm thinking kit kat because it's made to work with the small amount of ram, but...wanted to run it by you folk and see if you had any suggestions.
