I LOVE Deadpool. Had a pro, sold it with all intentions to upgrade to the premium, then other stuff happened which postponed that. I will have one back someday soon...not sure yet if it will be pro or prem. Awesome game, pure fun. You have to appreciate the humor or it will get old fast, but if you do, it's hilarious.
That said, Jurassic Park is better in every way. It's a kitchen sink game for me...it has it all. Amazing and unique shots...a mixture of close/far/easy/difficult/flowy/sniper/etc shots. It doesn't shoot like anything else out there (though the same could be said for DP). The code is amazing, and works so well with the playfield. There are so many ways to play it, all satisfying, and enough depth to keep you busy for years. I love the art, AV assets, etc. Everything just comes together 100% for me. It's amazingly fun to mod and personalize. Etc, etc. It is everything amazing about modern pinball to me.
I'm a little surprised that you eliminated DP premium from the running, which is an upgrade that changes the game in a fairly significant way, while keeping JP premium in the running, which adds cool gimmicks, but really doesn't change the gameplay much. I went with JP pro, and most will think I'm just justifying my purchase, but I honestly do not see the value in the upgrades for this one. With the pro I was able to swap in a completely badass looking Papo T-Rex, which when combined with the lighting and flashers looks 1000x cooler than the ugly stock brontosaurus head. The ball eating trick is super-cool when it works, but I'm happier with the overall aesthetic improvement even though mine is static. The raptor pit is also cool, but again a dropping wall of targets just doesn't justify the cost difference for me. And no, you cannot just easily backhand your way into raptor multiball as it takes at least one (but might be a couple?) shots all the way through to the back target, and that can't be done consistently from a backhand. Yes, the premium pen is cooler, but just not that much cooler. Spinning helicopter blades can be modded in. Not sure how much difference the sound trigger makes, but my switch does trigger a copter sound when shooting the S ramp. It just isn't timed to the blades. Again...kind of cool, but not a game changer. If money were truly no object, yeah I would have gotten an LE (I think the art is amazing on that one), but in the real world, I just couldn't justify those gimmicks improving the game enough to upgrade. Deadpool is different in that it has a completely different shot path, opening up a repeatable flowing shot that isn't there on the pro, plus adds a completely different mode to go with it. The rest are just gimmicks to me (drop targets could be argued either way), but they do combine to be worth the upgrade in my mind. In the end, I may end up with another pro, and be happy, but this is one of the relatively few cases where I think a premium upgrade could be justified.
As always, just my opinions, and I can definitely see why many prefer the JP prem/LE.
