Pedro had a better assist per minute ratio in 10/11 than Xavi and Iniesta. Does that mean that he was the superior creator?
And no, I'm not implying that Xavi and Iniesta are to Pedro what Messi is to Cristiano. I am just giving you an example that "more assists" doesn't equal "created more goals".
Technically speaking, an assist is just the second to last touch in a successful attack. Cristiano in his most successful years was a player completely focused on the final third of the pitch. Not only that but the entire tactical set up intended to get him at the end of attacks so it's only natural that he has many second to last touches before the ball passed the line.
But there are so many different patterns of attacks. Throughball, square, tap in. Throughball, finish. Switch of play, cross, header. Switch of play, dribbling, through ball, finish. And so forth. If you had the last, second to last or whichever contact in an attack doesn't say anything about the quality or importance of the play. Look at Neymar's pre-assist to Mbappe before their second goal against Atalanta. Neymar won't even show up on the scoring sheet but the way he postures himself with that little feint to set the defender on the wrong foot and plays a perfectly weighted and directed no look pass.. Sure that was good off the ball movement by Mbappe and Choupo-Moting but that goal was created 90% by Neymar.
And that's the stuff you very, very rarely see from Cristiano. His role is more that of Mbappe in this scene. Make a good run behind the line, receive the ball and square/cross it for a tap in. But that he plays one of those chipped passes behind the line, a through ball, creates superiority through a dribbling or a great one two in the build up - that's not to be seen often since probably 2013. On the other hand, Messi has evolved that aspect of his game further and further to the point where there's no other player as good at that as him. The fact that he still maintains a goal record that's at least on eye level with Cristiano's, CL knockout goals aside, is actually insane.
So yeah, I do rate playmaking that highly and you're right, due to that it's not really a discussion for me. That's what I've been saying since ages and what's "ridiculous" in the eyes of many of your peers
