Sorry to be a bit pessimistic... It's hard to beat the success and proven durability of a properly installed EPDM (ethylene propylene diene monomer [M-class] rubber), roofing system. It has a proven long history on commercial buildings and RV's. So having a more traditional EPDM roof system would not be a negative for me.
As to being happy to have the new style roof material as opposed to traditional EPDM. Only time will tell if the improved new, lighter material is better or worse.
I recall that Fleetwood/Coleman marketed the one piece pop-up roofs as the best thing since sliced bread. Time wasn't so kind on those.
In searching for how long Alpha-ply has been around I found this.

Just another of the many reformulations in TPO’s jaded history… each reformulation is the next cats meow in roofing…
TPO has been reformulated at least 5 times and each mfg has their own version of the new formulation, I don’t know how anyone knows what to use with it… one things for sure when you work on TPO or even install new TPO you don’t know what formulation you are working with, and none of them have a history to base which is good, better, or worse… I assume the reformulations are because of problems or failures of previous versions…
Alpha-Ply I believe is the second attempt at non-backed TPO… I wouldn’t want it on my roof until they can figure out a formulation that is good for the long haul…
