out of all firebenders he is the only one known to be able to breath fire, bend lightning and redirect lightning.

^ exsactly

^^the triple threat :)

same here, iroh is also one of the nicest friebenders therefor i kinda want him to be better if u know what i mean?

I like Iroh too, but Roku was the AVATAR ppl, and Iroh isn't the only one who could breath fire, Zuko can, Azula can, even Aang can, and if Aang can then roku could too, since Roku is Aang's past life, so I think that Roku is the best.

roku is the avatar sure which means he would win in a fight using all bending skills, but just focusing on a firebending fight, iroh would win hands down. He is more skilled in firebending then roku and the only way roku would win is if he used the other elements or went avatar mode.

Roku has the experience of hundreds of other firebenders all combined - when in the avatar state anyway. If he isn't in the avatar state I would pick Iroh.

^Of course we mean NO Avatar state and no avatar abilities, just restircted to firebending...remember Roku lost firebending duels to Sozen all the time when they were young.

well i think avtar roku to because he is one off the avtatars
