Having just purchased a GoT pro and my friend who bought an le I can safely say Stern has produced a top notch pin. The spike system is excellent with stereo sound and audio out. The decals are 100% (which they should be). Zero issues and the clear is the best I've seen. On par with my wozrr. My WOZ by the way had a couple of small issues that I had to fix so one up for Stern from my end.
Ghostbusters I would consider if it's not Lonnie Ropp coding. Plus obviously the layout and art etc. but Stern quality control has certainly improved.
I concur with regard to the QA over the past 3-5 years. More a case of the competition, but my KISS LE is still perfect. I was not expecting this to be the case, but I can't find "anything" to complain about.
