There's no winner—it's like asking if a wrench is better than a hammer. Spring water is for drinking and tasting. Distilled water is for purity and appliances. They live in different drawers, okay?
If you're stuck, think: "Am I drinking it, or am I cleaning a thing?" If you're drinking it, spring wins. If you're cleaning, distilled wins. Simple.
And don't let anyone shame you for buying either. You're hydrating or maintaining. Both are noble causes. Now go drink some water—spring or distilled, I don't care, just hydrate.
