I had the Philly cheesesteak. The meat was properly seasoned, not too salty not too bland. The bread was soft and fresh. The mayonnaise was just enough to really kick up the flavor and of course, the cheese was completely melted and mixed with the onions to perfection.
Between here and capriottis... I couldn't say who did it best.
