I snap them not to cook them easily (I know how to cook full length spaghetti) but because I find them easier to eat at this size. Less knots, fork spins and slurping needed. Also yes, easier to cook since the fits and you don’t need to supervise beyond the first mixing to avoid them gluing to each other. Better personal enjoyment overall.

I recommend you try it at least once. Cooking can be fun and creative, don’t let dogma limit your experience :)
