MOD is located right near Pie 5. They essentially have the same concept, but Pie 5 wins it in my view.
MOD has plentiful and creative toppings. The staff is also plentiful and nice (albeit disquietingly loud -- they shout hello and goodbye to patrons in unison). There's lots s of seating in a good looking restaurant.
Where MOD falls to Pie 5 is in the crust., which is more of a traditional pizza crust whereas The MOD crust is more like a giant tasteless cracker. The pizza is fast because the crust is thinner. Or it's supposed to be. My experience with Pie 5 is that they're as fast, if not faster. But they do theirs on a conveyor through an oven as opposed to the more traditional oven at MOD.
