Okay, no. Yuuki being surprised that magic is capable of being cut by swords does not indicate that Kirito is stronger than her. That has nothing to do with strength or skill, but a knowledge of game mechanics. Given that she is proven faster than Kirito and Asuna,  she could easily replicate the feat herself if she had known about the game mechanic beforehand.
