Nope, even if Real won the league Messi would have still been the better player. I am talking about their individual performances, the hat tricks and super hatricks that Messi scored against some really good teams, Ronaldo was mostly scoring against the Almeria's and the Getafe's. Messi scored more goals and indirectly assisted more goals than Ronaldo, he was undoubtedly better than Ronaldo throughout the season. He had a much better season, i really think your being very harsh on Messi by saying he only performed better in the Classico.
How about the round of 16 in the CL, Ronaldo went missing against Lyon while Messi completely destroyed Stuttgart.

How about the games in the group stage where Messi went missing against Rubin while Ronaldo completely destroyed Marseille
