Not sure how well this poll gets to the real question... Seems to me you're asking for a good pin to purchase for your lineup, that will be more friendly to new/casual players than your current pins, but will challenge you as well.
I'd say Metallica may be one of the best choices there - easy fun bash toy for noobs, crank it up goals/item collection for deeper play. Plenty to shoot for.
Iron Maiden is another good one. I find it both more inviting and more enjoyable than my TWD for instance. Plenty deep with goals that are achievable yet challenging for many different skill levels.
Rarely do I find either of these games to be frustrating, but they also keep me coming back for more.
