Itachi still pawns..he was head of ANBU at 13
This is a toss up for me. It depends on if Kakashi can get out of Itachi's regular genjutsu. If he can't then I might give it to Kakashi but I am not sure.
Speed- Itachi
Intelligence - about even, probably give the edge to Itachi.
Strength - ? Neither of them are known for their physical strength so I guess this is a draw.
Genjutsu - Itachi obviously
Taijutsu - without the sharingan they would probably be pretty evenly matched
Ninjutsu - Kakashi has a larger arsenal (possibly, remember he only got that through the sharingan, and Itachi could have copied any number of moves so who is to say he didn't?)
Elements - Kakashi has the elemental advantage of earth vs water and water vs. fire, and then he has lightning on top of that.
Chakra levels - about even or give it to Itachi. Itachi made a curse mark Sasuke who had absorbed Oro run out of chakra.
So even without the sharingan, Itachi is just a bit better than Kakashi. Kakashi's only advantage is the elemental strengths he has, while Itachi has the genjutsu advantage and the speed advantage.
EDIT: I see some people are underrating Itachi. There has been alot of that going on.
Someone said some BS about Itachi not beating Oro without his sharingan. That is false. That was a normal genjutsu Oro was in, not Tsukuyomi.
Itachi vs. Deidara, a normal genjutsu again. Deidara lost fair and square.
Itachi was a captain of the ANBU at 13, which is how old he was when he killed the Uchihas. He was massively talented and was stronger than most of them even without the sharingan.
Itachi would lose to Jiraiya if Jiraiya was in sage mode, but Itachi still would have genjutsu, which is Jiraiya's and Oro's weakness. Probably Tsunade's as well since that seems to be a theme amongst the Sannin.
Itachi still has his regular genjutsu, speed, average chakra levels, and intelligence. Be honest and tell me how many people have beaten Itachi's regular genjutsu. One? And that is only because Killer Bee is a perfect jinchurikki and he had Samehada. No one else had gotten out before Itachi could have killed them. So hate on Itachi all you want, facts are facts. And don't forget that he doesn't need Susanoo to use the Yata mirror or the Totsuka sword, since they are real weapons.
