I mean, I can't miss. ... I'm on a team with super-humans. And one god, in case you've forgotten. Even you...well, you climb walls really well. ... I gave up a lot for this life. I could have been happy with Mockingbir-- Bobbi. We could have had a good, simple life. But I wanted to play with the big boys. And if I miss it means I'm just another dude with a bow. It means I've been fooling myself this whole time. And that's why I never miss.
--Clint Barton (Earth-616)
If you're a fan of the Marval comic books or the movies, you know who Clint Barton is, he's Hawkeye, the world's greatest marksman and he never misses.
Not every character can be Hawkeye though. I'm not saying that they can't be the best at their job, I'm just saying that Hawkeye was unique because of his talent. Whatever else Clint Barton might have been, he was known for his skill as an archer.
I feel obligated to point out that Hawkeye works because his universe worked for him. Therefore, it is not that you can't have a character who is best at a talent, but that they have to exist in a world where them being the best works.
