I played the Pro tonight. So my first impression was... winner. I only played it once, so couldn’t get deep into the rules, and it was hard to hear the callouts. However, it was fun, and made me want to play it more.
For me, THAT is my entire criteria judging a game. Did I have fun and enjoy it. And this as a solid yes, so now I want to play it more.
As for the question of this thread, Premium. Totally for the T-Rex interaction with the ball. That one feature is exactly what Stern wanted it to be. It’s the difference that will make people spend more for the Premium. But the Pro was still fun.
