I currently own both models. The extras on the premium are cool. If you buy to keep a pin for a long time then over time you will enjoy the T-Rex, spinning copter, and raptor pin, etc.
But the game play is essentially the same so if you aren’t trying to build a higher end model collection and you just want to enjoy a really good recent Stern title the pro is not lacking at all.
Either model resells very well so honestly unless you buy stupid you can’t loose with either one.
