I haven't yet seen or heard the actual games in person, but after playing TX-Sector and Bone Busters on Pinball Arcade, and subsequently looking up a few YouTube vids...
...I have to agree with the comments on superior sound quality vs. B/W of the era. I own a Pinbot, Space Station, Whirlwind and Dr. Who which are rough contemporaries to TXS and BB- in some cases coming even later - and IMO the Gotts' sound is just way better. TX Sector has always gotten a lot of love for this, but I was amazed at how immersive and composed Bone Busters was. The "songs" in the Gottliebs have actual structure and progression and seem like they'd stand alone as individual 3+ minute tracks, whereas the B/W pins use standard loops and layers and chords. And once you get to the actual fidelity and quality, there's no comparison: GTB is better, ears down!
Of course I agree that GTB fumbled in other ways. Dr. Who and Cue Ball Wizard both came out in 1992: I had Cue Ball Wizard for a while and it was fun, but how did they ever expect that to "compete" with games like Dr. Who? CBW's sound is much better but its dots and animations (wait, did I say animations? Oops, there almost aren't any!) are laughable.
So on a feature basis GTB won some, lost some. I've enjoyed the few I played. My main complaint is that GTB callouts are far too repetitive and become tiresome, but then the older games don't have that problem.
I'd love to show some restoration love to an older GTB... or even a Bone Busters for "newer". After Louisville Expo I plan to get back to rebuilding my Big Hurt... assuming I can remember how it came apart before we moved last year...
