Winner

Spaghetti Squash

78/ 100

Spaghetti Squash wins for its unmatched pasta-mimicking texture and higher Vitamin A content, but Luffa offers a superior flavor-absorbing sponge quality for soups and stir-fries.

Spaghetti Squash scores higher due to its broader culinary appeal as a low-carb staple and its beta-carotene content. Luffa is excellent but limited by availability and a specific safety caveat regarding bitterness.

You trade the satisfying, strand-like bite of Spaghetti Squash for the soft, sauce-soaking brilliance of Luffa.
