actually, most of anime fighting kids have the same fighting style, so you can't compare just with that...

but the two animes are really similar to each other:

Kurapica- last survivor of a clan with red eyes who hunts for revenge - Sasuke.
Gon and Naruto have the same voice actor, and they both have a rather similar characteristics.

but on the other side, i must say that i find the HxH team much more 'flowing' together with eachother than team 7, they don't annoy the hell out of eachother all the time..

HxH has a small number of characteres (less than 10 improtant guys) while Naruto has about double (at least 20, and more are introduced).
