The more I played DI, the less I liked it. Was very enamored with it at first, but that quickly faded. The more I played DP, the more I loved it. DP has truly evolved into one of the best modern pins with it's unique layout and ruleset combined with amazing art, A/V, and humor. I personally found the premium upgrades to be nice, but not worth the extra money to me. YMMV there depending on your budget. Pro is still great and does not feel like it is blatantly missing anything.
