Default [Q] BetterBatteryStats vs GSam

Which do you guys prefer? Which would you say is more accurate overall? Which is better at detecting/hunting down wakelocks? I've been using GSam since i got the S5, but that was before root was available. Now that root is available and wakelock detection is a possibility, I'm starting to wonder which is better at it and just overall.
