"I'm pretty good at what i do, but what i do...
...is done better by other people."
Name characters who arent the best, who are just, well, pretty good, at what they do, in-universe and/or comics wide.
I'll throw my hat in the ring with Moon Knight:
As a street level vigilante/creature of the night character he's pretty good.
He's had some really good showings, several good to great series runs, a solid skill and power set, but, he's not the best.
In-universe, i'd definitely rank Daredevil over him, in all those categories.
Comics wide there's well, Batman of course.
