As that post said though, Juggy wasn't well. And come on. It's Juggernaut. He tossed Thor and Hulk around before. All Gambit did was bring debris down on him. Ussop can do that. Despite both being in that peak human range, Ussop seems to be the faster and stronger of the two. Ussop's marksmanship is probably on par with Hawkeye. I think he can tag Gambit first and has the agity advantage. Close quarters though he might be disadvantaged due to Gambit's kinetic charge. Could go either way.
Not Luffy level. But he isn't a normal human. He leaps around and such like a superhuman. I think he has even tanked canon fire before. Oh and he also survived numerous blows from Mr 4 with a 4 ton bat.
