I have both and the Flintstones would leave last. I'm on my 2nd Flintstones and ~immediately~ had sellers remorse and had to replace it with another one. It's really a fun game with a super nice playfield design. Popeye is fun too, but set at 3-ball, I haven't been able to make it very far. PSTE has some pretty deep rules. +1 for the Flintstones.
