To me Creech has the better art package, but that terrible tingy music that gets old real fast. Game play and rules are OK, but it is fairly easy to have excessively long ball times.
BSD is by far the better playing game and also to me has a way better rule set. Stacking multiballs was not very common at that time. Music and sounds are top notch. The cabinet looks nice, but the translite and playfield art are pretty much amateur hour, but it did take me some time before I'd had enough of seeing it everyday.
That being said, BSD was a much better playing experience of the two and got way more playing time when I owned it.
