He's faster. Only reason for me. 5KS Sasuke is the best Sasuke in the game IMO just because hes fast. Just like 5KS Naruto IA has the better moveset. --- http://i.minus.com/i72lUFXLsmKVy.gif In the end..All will bow down to Tenten The Great.
Lol. EMS Sasuke's tilt is far better than 5KS Sasuke's. but to answer your question:
Faster combos, Less hits when the opponent is guarding (which means less vulnerability to counter-attacks) -- and that's about it really... EMS Sasuke excels in everything else, including the awakening (obviously), NMC into Ougi move, safer Ougi start-up. --- GT: MadaraTheViper1
