Well probably I'm gonna get flamed for this but anyway, for me I am looking at the Konoha 11... and Sakura became a hell of a pretty good shinobi considering the fact she has no Kekke Genkai, literally none.
She's the only Haruno we've ever heard about, nothing more was told about her clan, she had nothing impressive all that she did was train. And got where she is because of that training and now she's one of the top tiers in Konoha 11.
As for the older ones, well we don't know much about Minato, but he could be considered another one cause we've never seen a Kekke Genkai on him. All that he did was just invent his own jutsus, a pretty impressive feat, and combined them with Uzumaki's sealing jutsus and that made him one of the top tiers. And with no Kekke Genkai...
