rai You have a nice and varied collection, so I think SW would fit in fine. SW might not last in a small collection. The shots and drains can be frustrating, but I like the speed of the game and it's become my "go-to" machine when I want a little punishment or to practice skills. The code is a mixed bag as well. The modes aren't particularly deep, but there seem to be some neat strategies on maximizing scoring and the light show is one of Stern's very best, especially during hyperloop multi ball, Boba Fett, and light saber duel. I really like the moving shot multiplier target and the hyperloop, even though I'm not great maximizing their potential. And there are lots of little accomplishments to achieve as well.
I'd rather shoot SW than DP, but I think DP is more fun as a game. Though BM66 probably has deeper code, most days I'd rather play SW because it's much faster and more challenging. IM probably has a better layout and is more fair so it's better to play on route or at someone else's house, but I'd rather own SW because of the theme, visuals, sound, and hyperloop. I can't really speak on GB or JP as I've just never been able to get into GB and I haven't played JP yet.
If you do pull the trigger on a SW, I'd get the premium with the comic art unless you could snag a much better deal on the regular premium, which might be the case. Good luck
