Baki vs Captain America
Baki is likely faster and is quite a bit tougher and stronger.
He was step for step matching Pickle for example even when Pickle was doing that disappear and reappear on the other side of the arena thing. He can also get shoved through multiple concrete walls, metal doors etc and still be mostly unharmed.

Baki is way faster and a bit stronger.
Steve will put up a good fight but he goes down.
Ultimate Cap would fare a bit better but it would just prolong the beat down.
