I played one when it first came out, and as a GP fan didn't mind it at all, especially the ball lapping the machine. It was the first of the Stern's that had a more familiar "williams" style feel to it, no doubt due to so many having moved across at that stage and started to influence game design/play.
Thanks for your comments, yes this pin does have a "williams" feel to it, playfield is not too busy, lots of good long shots, it ticks all the boxes for me, another great Pat Lawlor design..
