Quoted from jimwe5t:
You’re right on the money on this one. JJP quality is a myth, it doesn’t exist. Stern’s machines as a whole work all the time.
Based on my experience of operating games.
Best (least headache, PITA, adjustments needed out of the box, ease of maintenance, good parts, etc...) to Worst (often broken and critical failure out of box, continual headaches, cheap parts, premature failure, etc...)
The best = CGC and Spooky
The good (not happy with recent pf issues but they are not the end of the world and the parts are solid and QC is great post the original WOZ run) = JJP
The worst = Stern (node board failure, constant pf issues, flipper failures, cheap metal that is breaking in <500 plays, and often multiple game critical failures that render a game a 240lb paperweight while waiting for parts)
