Actually Thief has top DPR now thanks to additional bonus action.
its not all about DPR tho.
You'd be surprised how many D&D players would disagree.
I've had long arguments (in real life and online) about how I prefer to play an 'interesting' but weaker character, and been roundly berated for not calculating the DPR and maximising and therefore being a burden to the rest of the party.
I even dared play a social rogue once. The horror!
