I think most can at least remember 1 year out. For instance I think most remember that AC won the Giro, RdS, and then was 5th in the Tour. Most also probably remember that Quintana placed 1st in TA, then only managed a 2nd and 4th in the two gt's. Seems pretty obvious to me who was better.
Winning TA is much better than winning RDS on any objective parameter, first of all. And
obtaining 2nd in the Tour often, and, looking at the numbers, probably in this case as well, requires better or equal numbers to what you need to win the Giro. 5th in the Tour is, on paper, better than 4th in the Vuelta, but Quintana was way closer to winning or at least getting on the podium (despite being ill in a significant phase of the race). On the other hand, Contador was never any threat in the Tour. So it is hardly obvious who had a better season, in my opinion. Performance-wise I would probably back Quintana (although not by a big margin), but I realize that winning a GT might put Contador slightly above in terms of results.
All of this is, of course, assuming you believe Contador had a better season, because it appeared that way in your wording.
