First, there's room for everybody. Second, price point on Stern Pro's and the significantly more glitzy GnR LE is $3,500 difference.
I already own Hobbit and PotC. I was considering GnR but it offers nothing to entice me as far as shots, layout and gameplay go.
People complain about Sterns being too lean, cheaply made etc...but one could also make the argument that JJP is a bit over the top with features and could have de-cluttered the playfield of GnR a bit. It's got a giant movie screen showing concert clips of the middle-aged GnR. Great, but if I want that I'll watch a concert movie of GnR. It's got full-length songs. Great, but again if I want that I'll listen to Appetite on my stereo.
When I play pinball, I want to play pinball and have clear, challenging shots and objectives to try to master.
In the past year, I would argue that Stern has moved their shots, layout, conception and execution to the next level. Particularly: JP2; EHOH; Turtles and now AIQ.
Admittedly, quality is a little on the questionable side but then again Sterns pros offer great "value" for $6,000 IMO.
JJP are the "Ferrari" with all the features and goodies. I have 2 already and I don't need more.
IMO, Stern is breaking it open with clear, genius layouts and well-thought-out codes, modes and shot geometry.
Both companies are "great" and to each his own...but at this time, I think Stern are cranking out some all-time greats.
I'm out for GnR but can hardly wait to see what Steve Ritchie comes up with for Led Zep! GoT is ugly as shit, but I LOVE my LE and will probably never part with it.
