It's Contador in my view, and there's not too much of a debate. 9GT wins vs 4. Won without a strong team, and when there was conflict in his team. Won all three GTs, not just one. I mean honestly:
Peak Froome (2011-Present): 4GTs, 10 GT stages
Peak Contador (2007-2011): 6 GTs, 7 GT stages
Those aren't really comparable given that Froome's peak is nearly twice as long. I've never seen Froome blow away his rivals when his DS was against him (Contador 09). I've never seen Froome battle his rival, mano e mano, for an HC climb, without support, and win (Contador Tormalet- I know he didn't win the stage but he didn't concede time, which was his objective).
