I've been hesitant to move to 4.3 & 4.4 due to people's complaints about bugs. Finally took the plunge last night with Slim Beans stable 4.3 build. Wow, to say it's impressive is an understatement! It's got more options than sorcery and snappier than it's ever been, it's like a brand new phone. My hats off to the dev, I'm kicking myself for not upgrading sooner.
