I can't compare with Carrasco as I didn't watched him since he left Monaco. But Mbappe doesn't pass player with dribble. He's not turning with the ball close to his feet while still running at his constant speed or full speed. Mbappe is someone very intelligent, he knows his weakness so you don't really see it. He making mostly feint like Ocrin said, fake shots, fake crosses. When he making tactical dribble, he stop running and make static feint mostly, then run and pass them because he's faster even on short distance.
The most he showed is a 84 I think, and that's not a consistent part of his game. He has the potential to improve this part of his game, but yet that's not really his strenght.
