Quoted from jgentry:So if you are just looking at it based on games JJP has been very successful. As a business it's been a borderline disaster.
Sure. Stern has decades of experience. JJP is new. Pros and cons for both. Stern has proven (safe?) designs and quality, with an established brand. JJP has fresh/young blood gaining experience each year. Young designers with out-there designs. Sure, some ideas did not work. But JJP is also way more transparent. We know what failed design-wise because JJP opted to show us their design early.
I like all companies and hope they all stay afloat. It offers us more choices.
If I'm allowed to stir the pot a little though; JJP's design is risky and innovative. I mean, a rocking ship upper playfield? Name another innovation that bold in the last 5 years?
