Always on the lookout for the next best rom and I am always flashing new ones to try out so I have used quite a few. Recently i sbf my droid x back to stock and let it update to stock gingerbread so i can return it due to dead pixels and so far I have noticed a drop in battery life. I have tried all the listed roms above and battery life had varied on all. I should add that i run all the sam apps on each rom so no difference in apps or usage. This isn't a comparison of functionality between these roms its just battery life and what you have experienced with all or any. Feel free to add roms you think should be on the list.
Inorder from best battery life to worst:
