Yeah Sasuke got owned in that fight. However...
- Sasuke was still not 100%, he was still recovering from his previous fight.
- Sasuke was aiming to capture, not kill. If you know anything about Sasuke, you'd know that a lot of his techniques aren't necessarily suited for capture.
- That whole fight was basically a training exercise for his eyes. He didn't even use Amaratesu until the end, he didn't even use Susanno at all.
MS Sasuke that fought Danzo would beat Bee in my opinion. Not a stomp though.
EMS Sasuke stomps Bee.
