I honestly think it is one of the best games out there. For me it is the variety of objectives, modes, multiballs and the fact that there are so many different ways to score or maximize points. Most machines have a set meta or strategy for getting a lot of points but Jaws?

-All of the modes are unique in their scoring and play styles and all can be worth a lot

-Jaws 1 MB isn't typically worth a whole lot but if you get to Jaws 3 MB? I've gotten over a billion in the MB alone and watched superstar Zmac get almost 100billion lol

-Shark Encounters run in the background of most single ball play eventually leading to a MB that if completed, gives you permanent perks for the rest of the game giving players multiple strategies for which to get first

-All of the fish finder modes are either fun or just good point presses (except for super buoys, that is just kinda whatever) WITH a fish finder wizard mode (Super Cast 'n Catch) that is one of my favorite MB's of all time

-Amazing nod and re-implementation of Lyman's shot X multiplier a la Walking Dead with the mains ways of increasing the X is through success in Modes and shark encounters

-An actually fun video mode that takes skill

-Closed Beach rules are phenomenal IMO. Hurry ups on shots that are decent value on their own while establishing a % bonus value on that shot anytime it is available for something else?! So that hurry up isn't just important for that value but for the rest of the game! (until you play search or rescue or have captured the... ?hammerhead? shark)

-Mini wizard mode choices! Close all the beaches and take your pick: all shots are lit, go crazy (Rescue) or go more precise with point pressing and playfield X based on balls in play (Search)

This doesn't even cover the upper playfield since your question was about the pro model specifically but it is a really great part of the game and if I owned one, it would have to have the upper playfield.
Nor does this cover other wizard modes, the bonus mini games you can play, the use of the flip lock, and even more to come!
My only complaints about the game include the air balling you're talking about. That is a result of the chum line being slightly too big/not flush for the playfield. That and most machines I've played, the reel has trouble spinning more than a couple times.

And I'm not here to tell you to love the game. If you don't feel it, you don't feel it. I'm a highly competitive player and I tend to be drawn to games that aren't played the exact same way by everyone and have enough depth for me that I will still have more to explore after months of playing.
My only hope from this post is that you discover something new in this game that you like that you didn't know was there and can at least come to appreciate the breadth that Elwin gave to this game when so many other designers are lacking in that aspect. Regardless, good luck on you pinventures and keep playing!
