Kurapika is definitely on top even without the use of his Chain Jail (Which I think most people forget is the only chain with the Spider-only restriction). Killua makes second place, his martial skill and intellect is just higher than Gon's overall imo. Gon is third, no doubt that he will become the strongest in the time timespan of an arc but for now he's below Kurapika and Killua. Leorio has realistic goals and expectations so he isn't exactly a superhuman but hey Kuwabara from YYH started off weak and he grew to an A-class spirit level by the end of that series so I expect something great out of Leorio.
