To each their own. But if I'm hunting, I am not wearing PVC. I live and hunt in the Westcoast. The newest of the membranes have all been working well and the Chugach has been substantially better then anything I've used in the past. I think I have 6 seasons on mine, maybe 100 days in the field and it doesn't have any significance damage (though I'm pretty careful with my gear). I've skied in it, sailed in it, hunted, hiked, etc. the stuff just works.
I did a 10 day hunt on Haida Gwaii, 10 days of sideways rain and I couldn't complain about my gear once. We could get the gear 75% dry at night. My brother wore the Sitka gear and he was wet everyday.
The only way I'd wear PVC is if is was riding a quad or as a backup set for camp chores on a very wet hunt.
