Who is stronger?

[Jackalsblood]

Kakashi is way stronger  

[W. G. ZERO]

gai is stronger duh  

[Kittori]

Well they're both different you see.
Kakashi is obviously more stronger because he has the ability to use his chakra unlike Gai. Gai-sensei is unable to but he has great determination and self pride which makes him just as equal as Kakashi in my eyes ^-^.

I think Kakashi messes around when he fights so he can copy stuff.........Gai just comes to kick a**............ sweatdrop  

[Soleninja]

Gai lol  

[larence]

i think Kakashi is better ninja  

[Joossy]

KAKASHI!

I have yet to see Gai get his butt kicked........... sweatdrop

i have yet to see Gai face anyone besides a Jounin, and don't give me that "He faced Kisame" he faced a guy that looked like him and only had 30% of his charka and Power.  

[Talisen ap Lleu Llwy]

Taijutsu only combat Gai. Other forms added in Kakashi  

[BluedragonJade]

Kakashi 3nodding  

[Kertis]

yes!! go kakashi..... he looks and is better overall.  

[kcana]

Kakashi is of course.  

[x20itachi]

Kakashi seems like a better fighter.
Gai is looking more so for a rival, while it seems Kakashi cares a lot less.
He can copy techniques with the Sharingan, while Gai cannot.
Gai may be determined and strong as all get out, but he obviously always gives it 110%.
Kakashi kicks some a**, normally, just about as much as Gai, but Kakashi plays around a lot.  

[x20itachi]

So, deffinately Kakashi.  

[Honh]

I think there's no real difference. It's all relevent to those who see it in one's own perspective. So Jiraya, haha just kidding. Though Kakashi would kick Gai's a**, Gia'd have a chance. I see no real difference in both of them.
