A high quality stick is probably the best way to play, when learned. zangi-moves are really easy with a good stick, and hellishly fast. It's a bit trickier to do a zangi move on a keyboard, bu tnot impossible. THat said, i think straight sonic drop followed by lock is faster on a keyboard than a stick. That is probably where a keyboard player makes up the most of their speed, but then loses it in the zangi-moves.
