Spiderman vs Naruto - Both are mascots for their companies, both have a young heart, and both are related to some kind of animal Naruto a fox, and Spiderman...a spider
Ghost Rider vs Ichigo - Both are supernatural hunters, both can change shape into a creepy form, and both have incredibly powerful powers from supernatural hosts. Ichigo the Hollow inside and Ghost Rider from Hell....
Honestly, I think Spider-Man is overused as a rep for Marvel. Easy to understand since the movies have made him even more popular among the mass market (though I don't see how, considering how f***ing emo he is [IMO he puts canon-Kakashi and canon-Sasuke to shame at the same time]).
I do love the effects, though, and I'm glad it's Naruto showcasing SJ instead of Z-Goku. (though, honestly, we need more classic SJ like Yusuke Urameshi)
