Spinning around made Xavi a huge thing and is not that easy, you need ball control and good knowledge of your environment.
You can't control games while not being able to divert pressure.
Pedri is actually more talented but lacks body mass. That's his only downside. Other than that he is a complete midfielder. Usually midfielders don't score. Even Tapellingham is not scoring while playing more deep.
His future is dependent on the ability to have some gravity(Gavi too), Xavi was very impressive in his physicality while being a dwarf.
