Naruto is too powerful for Gon. While Gon has a (dragonball Z) aura he still lacks experience. In actual strenght he might be on par with Captain Marvel but he lacks speed and intellect. The again Naruto lacks intellect too. Naruto still wins because of his 9 Tailed Fox. Naruto wins.
But now Gon has a super form that can beat Naruto. Gon wins.
DR
But now Naruto has a new super form. Naruto wins.

Naruto is able to use him because it’s a personal summons. It’s like a loophole you could say.
