For battery combined with no bugs, stability and speed I recommend thors rom, google tegraowners.net it's not on XDA. Carbonrom on here is a great rom too, I'd also combine it with thor's kernel.
Then last but not least, SlimBean rom! It's my current daily and battery with included kernel is very decent and it's the current AOSP 4.3 rom with the least bugs imo. If you really can't live with any bugs go for the 4.2.2 version.
Only bugs I have in SlimBean beta2 4.3 is graphic glitches in stock browser and gmail.. But it's absolutely doable, besides that it's ultrafast and the customisation options are sweet
