I was also thinking about this as well. I bought SM last month, before I knew of AFMr and because it was near mint condition. I owned SM before for a while, sold it and just picked up last month and added Color DMD.

I have a lot less playing time on AFM so I can't say if it's any better than SM?

I am probably just wait and see what AFMr looks like once they ship and if there are any PF issues or anything else that could be a demerit.

AFM will likely be in production for 2 years and will be on the re-sale market so it's not as if you need to make a decision right now.

I'm happy with SM but would add AFM if I had the room, maybe in a year I will buy one, the good thing is that it's not limited number for the middle edition.

My least favorite part of SM is Sanbman drop bank, Tron is not as bad because it has the spinning disc.

I love the Venom ramp, and Doc Oc magnet shot on SM.
