The Generator is much warmer with I think 100g primaloft so better as an emergency warm layer or full on winter belay jacket. I have the smock and have survived a number of bivis in the Alps wearing it and have used it for snowholing.
I also picked up a cheap Generator gilet and that works well for a packable core warm layer and for going to the shops!
I have the original Prism 1 which is lighter and more packable than the Prism 2, though it's no where near as warm.
The Prism 2 has two layers of insulation on the front compared to the older Prism 1 and is a lot warmer throughout.
I found the old Prism 1 to be too cold for a winter climbing jacket and more a Summer, Spring jacket. However I do use the newer Prism 2 for a winter climbing belay jacket especially on easier stuff that I can move fairly quickly on, as it packs small and light.
Other than the thickness of the Primaloft insulation and the resulting warmth, the Prism 1, 2 and the Generator are pretty similar or at least have similar properties!!!
