Quoted from BowlingJim:I have never seen a premium in person. I own a pro and love it but if I had the chance to upgrade to premium I would.
I had played a Pro on location for hundreds of games and it was already one of my favorite pins before I ever tried a Premium. When I did it felt like a whole new game with extra strategy, toys and features. I knew for home that the Premium/LE was what I wanted. The Pro is still an awesome game and one of my favorites but the Premium/LE is just better overall. Now the Pro feels so stripped down when I play it without the lighting effects, spinners, fish tank, etc. Still fun and I'd recommend either model depending on budget.
Also, the Pro is definitely the easier of the two models to play. My scores are generally a bit higher on the Pro. Sure, the Walker bombs can save you from time to time but the Premium just drains harder with the extra bash target and magnet.
