I would say Mayfield is clearly #1.
Allen would be my clear #2 if he had played more up to this point. We have not seen much but hard to have anyone over him besides Bake.
Darnold and Rosen I have very close, it's hard for me to put one over the other.
Finally, Lamar is creeping up for me, he has flashes but he's clearly behind the rest of the bunch at this point.
