Interesting idea. Personally, I’ve always thought that Kauto/Denman reminded me of Federer/Nadal.
Kauto= Federer, very classy and versatile, basically unbeatable when right, prone to slight lapses in concentration (or Kauto used to be), great longevity and thought to be one of the greatest of all time.
Denman= Nadal, mainly about power, but with a hefty dose of speed and skill as well, will simply bulldoze opponents into the ground, one of the few capable of beating Kauto/Federer, but less versatile (though Nadal has overcome this handicap). And sadly more prone to injury due to their style of running/play.
