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.
Spaghetti
A strand has no cavity and no ridges, so a sauce must coat it. Thin, slippery sauces win: oil and garlic, clams, a smooth tomato, a pecorino emulsion. A chunky ragu slides off and pools in the bowl. Rome dresses spaghetti with carbonara and cacio e pepe. Naples gives it clams and tomato.
Can you swap them?
Spaghetti for bucatini: yes, the standard strand, a lighter result.
