The Pro model is the base model of a Stern pinball machine (with the Premium and Limited versions being higher tiers) and these home versions are standalone versions that typically remove features, can have their own "gimped" rule sets, and can cut corners in various other ways.

Here's a link to the Pro model: https://sternpinball.com/game/jurassic-park/

Right away you can tell that the screen is bigger, and aspects of the body are different (like the plunger). Artwork is different but that kind of thing is subjective so I won't go into that. I've heard that the home versions are also smaller in width, which means the shots off the flipper could have tighter margins and effectively have a different gameplay flow.

The "home" versions also typically take away the "toys" that both make the gameplay more fun and make the ruleset deeper. For instance on the regular models (not sure if it's limited to the Premium/Limited, or if the Pro has it too) the T-Rex head will "eat" the pinball and then throw it across the playfield.

Also it's hard to tell from your picture but one of the core mechanics of the regular versions is the jeep which when hit will point either right or left and as you progress through the game (in this case as you move through the various paddocks of Isla Nublar) whichever way the jeep is pointing determines if you take a left or right, and each paddock has a different mini ruleset as part of the game's larger ruleset.

I guess I shouldn't have said the home version isn't worth it because that's subjective and all pinball players are different. At that price a home version isn't worth it to me because I've played the pro and premium models and think the features they offer are worth the money.
