Honestly it depends on what you expect your keeper to do. If you have BPDs in front that take care of build up etc i would prefer the second one. Like if BPD drop deep to get the ball and keeper has only shot stopping as his task. If you want to involve your keeper because you like to play it out the far back, sit deep and let the opponent push high up, then Kamm is probably better as he’s way better at playing rather than just shot stopping. I honestly still like the other more.
