A bunch of non-essential features won't sway anyone to get one console over another.
The sleep/resume feature is also coming to PS4. As for battery life.. X1 controller does well, though, it still runs on AA batteries and battery packs. DS4 one is lacking in that regard, but has built in rechargable li-ion (that, in my experience, are so much more robust than any normal rechargables.)
The most important factor is the games (obviously), namely the exclusives. And games performance.
