The man defeated Palpatine (George confirmed that it was for real), so yes.

VAAPAD is the coolest light saber form and it uses both light and dark side His powers were amazing and beating palps isn’t something to shrug off. Palps best yoda, so mace could maybe beat yoda. Also his light saber is dope

Knowing how much Master Windu would be so disappointed with my almost certainly terrible combat skills is probably what would lead me to study under Jocasta Nu in the Jedi Archives instead.

If I were actually martially inclined, YES. The way Windu was willing to get all up in the grey area while still honoring the light side is so dang admirable.
