ROTOR cranks haven't proved themselves to have any advantage over Sugino 75, Dura Ace, or Omniums for sprinters and Campy for enduros. But, they haven't proven themselves to be inferior either.
There aren't very many out there. I've only seen photos of one person using them on a track bike (Jack Lindquist). He's a pretty strong/fast guy. And I think there was a young national level woman sprinter in Colorado using them (I can't recall her name).
Maybe if ROTOR lowered the price and/or gave them to a few popular riders they would become more popular.
I'm riding a 130 SRM/Rotor. Nice crank. Not any difference in feel from the Shimano 144 I used or the FSA I had. The extra $$$ come from a lot of machining to make them light for the road crowd. YMMV, I'm not a huge watts guy and a 150-160# all arounder.
