TCW Grievous vs. Darth Nihl

Sabers only

Canon feats only for Grievous

If we assume it isn't big, GG wins emphatically. If we assume the gap is monumental - or at least very noticeable, Nihl has some wiggle room for a winning argument in his favor.

It also depends how much we interpret in GG vs Maul
