I like both machines, played SW at tournaments a lot but cannot say anything about longevity.

I own a beautiful RfM so i tend to vote for RfM.
I love the Pin2000 technology, in my opinion that was a real breaktrough in technology and it's so well tied into gameplay in RfM. Just very funny and charming. It's a basic fan layout and you progress linear through modes but the animations and excellent sound do keep it fresh for me, it just creates an awesome atmosphere!
Plus non pinhead guests just love this machine!
Cheers

Niiice!
Get the 3d translite from Henrik, pinballdreams, it‘s really beautiful! Other than that i think this RfM is maxed out
Congratulations
