I played both the pro and premium models at Replay FX. The T Rex on the premium moves around while you play before you activate it, so it seems a little more alive. The pro is just static all the time.
Home = Premium unless the extra cash is not worth it for you
Route = Pro
I only got one game on the premium because of long lines. I didn't shoot for the Raptor pen on the premium cause I wanted the T Rex to eat the ball and he did. It is very easy to active the T Rex, just shoot the Jeep a few times.
Looking forward to playing the premium in a home setting with compete code.
