I use Gsam and wakelock detector. Always have. Gsam is just laid out way better, and much easier to read. And wakelock detector just gives a more indepth look at wake locks.
I never recommend BBS when trying to help anyone with a battery issue....its not near as user friendly and easy to understand.
But to each their own....everyone likes what they like. At the end of the day, they're mostly all the same.
Except the stock battery usage screen.... It tells you nothing useful. Yet people always post screens of it for others to help find issues. And they always get told, download gsam or whatever and try again. Lol.
