As Mr Hofs mentioned, typically ROM comparison threads, while kind in nature, tend to stray into fanboi wars. For that reason we always close them.
But to answer your question, the only way to know is to try them yourself. ROM & Battery experience is very subjective and will vary between user.
My advice, take a few hours flashing and testing them, choose what you think is best. One benefit we have over iOS, we have that choice.
