If none of these themes alone compel you one way or the other- like me- than SW Pro is my recommendation. On the other hand, if you love a theme then that trumps everything else since gameplay is not SIGNIFICANTLY better or worse among the 3.
If you're not particularly crazy about one theme over another, then you seriously have to play all 3 for several (not 50!) games to feel what grabs you at the gut level, taking into account the entire experience- theme, gameplay, lights, sound, video. Do you rush to put more $$ in? Or do you pause and contemplate? GB was initially a blast to play, but then for some reason I became bored of it (or irritated?) and I stopped playing it altogether. I'm glad I didn’t buy it. AS never grabbed me, I can’t explain why (I enjoy AS music more than ACDC, but enjoy ACDC pin more than AS.) I had to stop and decide after every game do I want to make the $2/3 game investment here again or play something else.
SW keeps me pumping $2/3 plays in over and over until I have to go. To me- compared to the other 2 titles- it’s fast and immersive and the theme is interesting enough.…. And/but , yes, unfortunately it has a playfield that’s hard to justify for the price you pay NIB. At least the Pro is the lowest amount you’re getting “ripped off”, while still having more fun than playing the others. I’ll probably own a SW (HUO) one day, but not the other 2.
