Scuf controller fortnite?

I would like to buy a scuf controller, because my old controller is not working properly (running or running always breaks off in the game and it makes some difficult) so I came up with the idea then directly to buy another new / good scuf, Since I have not had any experience with it, I ask you what are your experiences? Since you have become better in Fortnite? And which is the best? I'm thinking about either the Impact or King Controller.

They are good, but they do not justify the price, you can do something with the backs and they are good for fortnite (I do not know) - then it could be a small advantage.
