If Guy can use it without any drawbacks, Guy stomps all of them. The only one I see that can stand up to Guy would be Naruto, but since Guy is much faster than Six Paths Madara, we can assume he is much faster than Six Paths Naruto. We also know Six Paths Obito beat the 4 Hokage (Hasirama, Tobirama, Hiruzen, and Minato) in speed, and Six Paths Madara and Naruto are faster than SP Obito.

TL;DR: Guy wins as he blitz's and one hits every Hokage (except for maybe Naruto, though he would still lose) before they even know what hit them, and he can use 8 Gates without any drawbacks.
