You may be trying tomatoes from the same region. Comparing North American tomatoes (personal experiences include Ontario and N/S California) versus European (Italy/Swiss), the taste, sweetness and juicyness, is more bland in North America. As for tomatoes from the same region, I've never really tasted a difference either.
