I'm on Fedora and it took essentially no time for me to apply FW's recommended battery life configs[1]. (I think on Fedora they just recommend default settings.) I don't feel the need to play around with anything at all; I get more than adequate battery life and no drain while suspended.

It's not exactly comparable to my MBP, but neither is the cost! The FW cost me about $1,100 all-in and the MBP was $2,900 (both 32GB/1TB).
