Hmmm.....

Sasuke doesn't have much to go with, imo- Pro-Sasuke people keep going on about "Sharingan" this and "Sharingan" that, when Sharingan (at Sasuke's current stage) is only a move that analyzes the opponent. That, and it's reportedly more or less useless on Taijitsu, as shown in the episode where Lee and Sasuke first spar for a moment- If the eyes can't keep up with the motion at all, they're useless.

Kimi can handle linear attacks really well, which he points out when he's able to block Lee's attacks, pre-sake. Chidori = linear motion. Kimi > linear motion. tf, Kimi > Chidori.

*edit*

Really, what would happen, is in the time for Sasuke and Kimi to go through flashbacks and speechs, Rock Lee would have had time to fully recover and train for a month, come back to the field, surpass himself and open the 6th gate, and plaster Kimi & Sasuke in one powerful combo. And then go after Gaara for good measure. XD
