Best / Most fun BL2 Vault Hunter?

Just finished BL3 and as fun as it was, I think I am going to try a BL2 play through, I kinda got bored towards the end. I purchased the Handsome Jack Collection so I have all the dlc.

What vault hunter did you guys find the best and most fun? I’m torn who to play.

Edit: 1) I love the borderlands community 2) it’s enjoyable reading everyone’s fav characters. One person finds Zero boring and another persons fav

Update - I decided on Zer0 because I’ve wanted to try him for a while, and honestly I’m having a blast going invis and headshotting people with a sniper. I just can’t decide between the melee build and sniper build later on
