Tomatoes in supermarkets are varieties that are optimized to survive transport and storage and are not harvested at peak ripeness.

But tomatoes from Spain and Morocco taste much better than those from Netherlands even if transport is significantly longer - how to explain it?

IME all store tomatoes taste bland because they were picked unripe for transport. That's why it's recommended to use canned tomatoes whenever you can, they are much tastier as they are picked at the right time and quickly canned.

That's not my experience.
