To preface this, I'll say I've been playing the borderlands games off and on for a long time, though I've never taken any of them all the way to the limit. I want to change that, but don't know where to start.

I've done my reading, looked over UVHM, OP levels, Mayhem levels, but I want to hear from the real veterans of the series. Which game is the best to go with for a first time taking a character to the limit? If it matters at all, 2 and 3 are the ones I've played the most, and the characters I typically go with are Zero and Flak respectively.
