IMDN is my pick for best pin ever, so I give Elwin the nod. But FF from Jack Danger looks friggin great. Looking forward to playing it. I don't really see it topping IMDN for me overall, just because I don't really like Foo Fighters music. But FF looks design wise to have more in it, and honestly it looks like a total homerun for Jack and crew.
Cold day in hell before FF tops Maiden music for me though, lol. Theme is important enough in general that this comparison is kinda flawed , IMO.
