Quoted from BC_Gambit:

Play both, decide. Not more to add, but I own a DI and a JP Pro.
DI is the best (or at least one of the best) "90's" game ever made. I would take it over a MM for example (and did ).
JP is a tough game that after a year of ownership and hundreds of plays I have not "beat". I am not sure I have even made it to the "when dinosaurs ruled the earth" wizard mode. I enjoy that game, but how to play it is not transparent. If you don't try to at least learn the basics, you will be standing there going "I don't get it. This game sucks"

Quoted from Guinnesstime:

Jurassic Park Premium is LIGHT YEARS more fun that Dialed In LE, which out of the 40-something pins I've owned, lasted the absolute shortest. Like 10 days. The design might be ok, but it's the worst theme and worst audio. It's completely soulless and generic and the poorly designed SIM card shot is a huge flaw in the game. The one positive is anytime you flip, you do hit something. No need to aim.

Quoted from nicoy3k:

you can make a bad choice IMO

Quoted from nicoy3k:

I did, sold it immediately because it’s not a finished game code wise.

Quoted from adol75:

DI is a joy to play, I've own mine for a year now and I enjoy playing it more than any other game.
It flows like no other game, the modes and scoring system are designed for that flow, it's smooth, fluid, an impressive achievement in Pinball design IMO.
I haven't seen all of it yet, there's some good surprises, the quantum theater is a toy like no other and I do enjoy waiving my hand in front of the camera to scratch a ticket.
Definitely underrated and top of my personal list.
