I would pick T2.

You called out the most important item when you wrote "I know this is very subjective". Intelligent people can disagree. With that said...

I own both JP and T2.

I've had T2 since 2005 or so. It's a keeper. Some people write that, but I've got the 15+ years of proof. I've found it's very reliable, has great flow, and is a game you can decide to play for 5 minutes or 50 minutes. What about depth? T2 is deeper than most think but no 90s game is as deep as a 2015+ game. Gun toy is great. Music is great. Has actual Arnold custom speech, none of that "fake actor" stuff you get now-a-days.

JP is another great game. I've had it since 2017 or so. No plans to let it go either (but no hard proof like T2). It's not clunky at all, but nothing as smooth as T2. One isn't necessarily better than the other. The Dino guy is a top toy of all time, but some have trouble getting it working reliably. I haven't had trouble. It's fast and furious, with more wild ball bounces. I like the music a lot (and am no fan of adding the John Williams music because I don't think it's a good match for the feel of the game). There's a custom rom you can get that makes the modes random, which some people like. It's a good option to have. Some people dislike the DE playfield artwork. While I definitely don't think it's amazing, it has it's charm.

I don't think you can go wrong either.

I don't have any opinions about No Fear or Breakshot, other than I've played them and never had a desire to own either.

I'd go JP with T2 being my second choice.

For me No Fear is the weakest theme but the best game. I also LOVE Breakshot but its not for a small collection as its easy to beat and will get old quick.

Don't buy T2, I'm still kinda looking for one. If you buy it, it's one less for me.

No Fear. Hope you can find one that isn’t faded to crap!

T2 was more fun, for quick games for me, and looks sweeter.
No Fear tweaked is a speed demon, and lasted longer.

T2 would be my choice. Great theme and deep for its age. Breakshot has the best match play graphics of any game but thats really all its got going for it. I really wanted to like that game but couldnt get into it. And its kinda got a bad rep for reliability. No fear wasnt for me theme wise, and i have no opinion on jp.

T2 with JP very close second.
Eventually have both as they are worth it.

O man… Jurassic Park, followed closely by T2. Note that you could trade between most of these titles later on. Jurassic Park was one of my first machines to rotate through my basement. It has a lot going for it. The Dinosaur eats the ball! 6 Ball Multiball, shaker motor! Trigger! Smart Missile! I really enjoyed the dots on this game and the sound is great… especially if you hook it up to an external sub. Chad 6.0 code randomizing the modes really changes up the game. It is a mode based game and is kind of a clunky start/stop game. Note that the layout is a complete ripoff of Whirlwind with very few changes, yet much less flowy. If you have kids in the house or have visitors, they will gravitate to this machine over the others… mine did.
Here is a walkthrough of the rules I made a few years ago on my old machines.

T2 is a great game. I looked really hard at a few at Pinfest a few weekends ago. The game is super flowy, but it is not a mode based game. Think of it as more of a late 80s A/N game that happens to have a DMD. The sound and voice acting is superb. If I were a league/tournament guy that wanted to work on my skills I’d go with this one.

Overall, the list you have is fantastic. If you rotate games semi-frequently, I’d grab the first good deal available of any of those listed. If I was bolting it to the floor, JP!

T2 is the best out of those four games imo.

I love 90s games but prefer B/W ones and avoid buying/owning DE as I find them chunkier and not as robust.

If you want a game that provides endless fun buy No Fear,
If you want a game with a classic license buy T2, which is still a fun machine ,
If you want a game that’s boring but has dinosaurs on it buy JP,
Nice one

As good looking as Breakshot is i vote Jurassic Park. What every reason you don't like jp you will have no problem selling/trading it. There are a lot of game play videos of all the games you thinking about. Yes playing is best. But some times that's not always possible so get as much exposure as possible.

Nothing worse to get a game only to discover it's not enough to entertain you. Or there is that one thing you just can't stand music or constant sound if does it seems to be 85% of the time.
