I’ve been around long enough to have a opinion: Stern sells allot more pins for sure.... mainly because they are cheap and they can crank out the volume. I’ve owned 10+ sterns and every JJP pin (and about every Williams / Bally A game). My advise is don’t fall for the hype and pumping of any pin here on pinside - go play the heck out of what your considering first. My preference - you get much more from JJP in terms of quality, code, toys, immersion, value, lastability, and your supporting a family run organization of great people who’s focus is building the best games in the world - unlike stern whose run by an investor group and their bean counters.
