Default [Q] ROMs For Given Criteria?

I know that generally speaking, opinion-threads aren't highly looked upon here.

That said, I am not asking, "What ROM is your favorite?" I am looking here to find a ROM that meets a certain set of criteria, and am finding it difficult to do so with the way that things are organized here.

These criteria, in order, are:
  • Stable
  • Quick
  • Good Battery Life
  • Featureful

So in other words, while I would love for it to have the most modern, high-end KitKat features available, I would not want to make big sacrifices to battery life for their sake. I would not want to make big sacrifices to the fluidity for battery life, and I would not want to make big sacrifices to the stability for speed.

So my question is: what ROMs meet these criteria best? Not what roms are the best -- what ROMs best meet these criteria?
