What was fight that showed off a certain style? Which fight showed off the best assets of a certain fighting style?

Off the top of my head:

Ali-Williams: Ali countered effectively and bewildered his power punching opponent, eventually knocking him out

Floyd Mayweather Jr-Diego Corrales: virtually the same as Ali-Williams but with the emphasis on DEFENSE as in blocking (not avoiding) punches.

What were the best fights for displaying the Peek-a-boo, the boxer-puncher, the slickster, the sniper, the pressure fighter, etc
