Bucatini
The bore takes in sauce, so bucatini wants a sauce with more body than a strand normally takes: amatriciana, a gricia, a tomato with guanciale, a loose ragu. Thin oil sauces run straight through it.
Spaghettoni
A thick strand releases more starch and stays firm longer, so it suits the Roman cheese sauces that need starchy water to come together. It also stands up to guanciale and pepper without going limp.
