Team 1 might actually win.
-CE Prelims Neji is apparently able to react to the 5G Lee well enough to tag him.
-SRA Neji has a 4 in speed while CE Prelims has a 3. After looking at more scores (and arguing in that thread :lol) it seems that the points represent tiers, so this is a pretty large difference. And he's overall much much stronger since he has Body Blow, 64 Palms and Rotation.
-So SRA Neji would react to CE 5G Lee well enough to use Rotation imo, assuming rotation is easier than dodging.
So if 5G Lee rushes Neji and tries to use Ura Renge then Neji would counter with Rotation and cause some pretty heavy damage. If Naruto hadn't switched with a clone when he clashed with Neji's incomplete Rotation (from an inferior Neji) he would've been knocked out, but that's because Naruto came at Neji with so much power in the first place. Lee might not have that kind of power but he has the speed to make crashing into Rotation and getting repelled dangerous. Then Neji can use the fact that Lee has been repelled like that as an opportunity to maybe land 64 palms. I'm iffy on all this though.
So Neji would take out Lee in CQC w/o Ura Renge according to Gai's statement and combined with the fact that SRA Neji is a good amount faster than CE Neji, and when Ura Renge is factored in, Neji has Rotation as a counter.
Meanwhile Sasuke already beat Naruto in canon, but it can also possibly end in a tie.
