Cavatappi
Three ways to hold sauce at once, so it takes cheese sauces, cream, pesto, dressings, and a light ragu. It is the upgrade from elbows in mac and cheese and it stays springy when cold.
Conchiglie
A cup fills with whatever is in the pan: cheese sauce, cream with peas, a sausage crumble, a chunky tomato. Medium shells are a mac-and-cheese upgrade. Ridges hold sauce on the outside too.
