Pizza bagels are worse than pizza rolls. You all crazy.
Pizza rolls contain the good stuff safely inside, assuming you can cook them correctly (which isn't hard fyi. I feel like
@Conefed had trouble cooking the stuffed Doritos without them bursting, too?). Plus they are sized appropriately to be eaten in a single bite, release the burst of flavor all at once. The problem with pizza bagels is that the toppings are all exposed on it, so you take a bite and the whole topping of cheese and meat just slides right the fuck off, leaving you with a slightly tomato-flavored bagel. Trying to eat a pizza bagel in a single bite always results in scalding cheese burning the top of your mouth.
Edit: And I know people will counter with the pain of the burst of lava-hot sauce exploding in your mouth when you eat pizza rolls. However, all you need to do is bite off a corner or two and it will let you ease the sauce out as you chew, so it won't hit you all at once like it will if there is no sauce escape route.
