Best Custom Rom Preserving Battery Life and Lower Resource Use

[huntnyc]

Not trying to pit one rom against another - have tried several and am very new to all the smartphone customizing and using phone. So I am just interested in your experience with what current custom rom gives you better battery life and resource use. I know usage has a lot to do with it but out of the box performance is what I am interested in - have you found some roms excel more in these areas and thanks.
