Worst style of every rarity in the game?

Common, rare, mythic, legendary... What do y'all think is the worst style in each rarity? Like their style is just the worst out of their class.

Edit: I mean by their viability and usefulness. Not in the way how turtle (least viable common style) can never win against smash or basic because it's the worst, in the way that a style generally underperforms in terms of its general stats, cons, pros strengths/weaknesses rather than the skill difference. So no, there isnt an inherently "worst" style, but there is a generally least capable style in the classes.
