I've had and enjoy both. I ended up selling Johnny just because the spinner rules were a bit too unbalanced and I needed room, but I still look forward to playing it when I visit

I'd get both I've owned them for over six years now and still enjoy them a lot.

JM is a lot more fun and a way better layout IMO, never really cared for DM, the left side of the playfield is pretty meh. JM has the killer speed and ramp combos. If the glove is rebuilt you should be good to go.

Isn't there an updated rom to balance the spinner scoring?

I much prefer JM. A dialed in Johnny is lightning fast. That speed for me never gets old. I also love the stratagy of the grid, getting power items from crazy bob's, yakuza strike and the awesome power down. For me its George Gomez's best game.

I reciently sold my DM. I like the handles and is fun to shoot. The upper flipper ramp shot is great as are many of the callouts. The code could be much better. The left side of the playfield is not worth shooting. Retina scan captive shot does not feel right / too light. The multiballs feel too similar. The dmd animations are limited. Art package is poor.

My trinity is JM, DM, and The Shadow. So, yes, please get both

I've always liked using the handles on Demo Man. I like the focus on combo shots and extra flipper games are always a plus for me. It certainly does feel like you're only getting 2/3rds of a layout, however.

Johnny is fast and I like the glove/matrix features. Shot wise I feel the game is limited (way more targets in Demo) although the ramps and orbits are great, just not much else to shoot for and I can get those similar shots in many other games.

I give a slight edge to Demo for the handles and the 3rd flipper/ramp combos. Johnny has less shots, but I favor the glove over the cryo claw and it's the better looking of the two games. Last Johnny I had I shopped it out and cleaning/maintaining the glove mechanism isn't as bad as one would think.

Both games have come and gone. But at the right price you cant go wrong with either one, especially if you favor 90s Williams. I'd say try to get both.
