Wow, fanboys?
The only reason people even like Sasuke is because of his Sharingan, or maybe just because he's an emo like most of his fans.
Raikage is the most impressive Shinobi we've seen yet in Naruto's universe. He doesn't even posses the Sharingan, a tailed beast or Sage mode. He's fighting against Sasuke with his own strength. And he even managed to gain the upperhand against Sasuke, and would've easily have killed him, if Sasuke didn't use another one of his cheap tricks which Kishi gave him.
Raikage, Jiraiya & Sarutobi, they're the greatest Shinobis yet. I would love to see how well Sasuke would fight against them without his Sharingan. Or how fast will Sasuke's current fanbase will reduce, if he should lose his Sharingan forever.
i like sasuke because i could understand what he did until the point where itachi died. and no, i am not emo

i dont like the good guys in the most stories, because they often are simpletons, like harry potter, luke skywalker, son goku, ichigo and naruto just to name a few.
raikage's philosophy is pretty much the same sasuke has, he's driven by hatred and doesnt think that the weak will survive. so either you respect his strenght (which jiraiya doesnt have because he needed sm to do anything to pain, and sarutobi was if i'm not completely wrong related to the senjus) or his philosophy, which is completely different to the one the other two have.
towards sharingan: yes, it is an advantage, but otherwise the battle wouldnt be fair at all. raikage as one of the strongest ninja in the shinobi-world has to be pretty talented as well, is somewhere around fourty years old and therefore pretty experienced, and had information about sasuke's jutsus and style. but basically you are right, raikage definately is impressive and probably the strongest character outside of the senju and uchiha-clan so far.
@topic: sasuke will win this fight, because he's one of the two main characters. itachi's skills definately are overpowered, but sasuke's basic version of susano'o is pretty disappointing, and raikage is at least equal to sasuke until now.
