You've invented that argument in order to make that point, so I'm not sure what the point was. The exact point that was being made was that Ronaldo cannot do the things that Messi does, there's no 'but' beyond that because that was the entire basis of the point.
Messi can't do some of the things Ronaldo does. That would be the case when discussing all-time greats.
That's where the dribbling past 4 or 5 players and scoring > dominating in the air debate comes into play. What Ronaldo can't do, that Messi can do is more impressive and harder imo. I think that's where the huge difference is.
KI nails it here.
Safe to say a lot comes down to personal preference and what you prefer in a player.
