I don't see how you can compare him to them at all. Whenever he gets the ball all he thinks about is shooting. He'll just try shooting from ridiculous angles when a simple pass to a teammate is the better option. he's not a good team player at all. Even for Portugal he does the same shit. Zidane was better than him.
I don't think he's a great team player is, and yes, he does shoot a lot (FYI - Messi does this too, to the tune of almost 40% of Barca's shots). But what he's doing with goals scored is just fucking incredible. Zidane was a maestro, a magician on the pitch - one of the top, if not the top, player of his generation. I just think the way footy is going & Ronaldo's goalscoring only set to continue (& probably improve), Ronaldo's name will be in the 'greatest of all time' conversation far more than Zidane's (rightly or wrongly)
