Well my point is that ST is the highest rated SR pin and many people own or have owned both AcDc and ST premium and in many cases SM which all have the SR flow.
I believe AcDc is just as nice overall and more interesting (to me) since it has real toy (cannon) and what I like is AcDc has specific areas of the game for specific modes. Whereas to me ST is kind of generic except for what shots are lit.
So I'm giving AcDc a higher grade myself.
