I'm in the minority, I'd choose Jokerz! It's a fun theme, fun multiball, good looking game, and pretty approachable for guests. I'm also not a fan of the double your score, but I guess that would make it even more appealing to guests. I'm also a sucker for mechanically animated backglass
Been awhile since I saw a Fire! Wow, that translite is really ugly. I recall enjoying playing Fire! and Big Guns, but not enough to own. I do love the fire effect on the playfield -- again a sucker for mechanical animation.
I currently have a Jokerz! in pieces. Plan on getting to that next. It's not the deepest game, but it just such a fun theme. When I hear it, I have to smile. It's some good 80s Sys 11 cheese.
Good luck in your decision!
