Most of the basis were covered in that thread, DryQ is eVent, eVent is good. if your jacket wets out it isn't really breathable anymore.
The shell I use is an REI brand eVent shell that they sadly discontinued (fortunately I have 3 of them). It doesn't even have pit-zips which I like, I have yet to feel I've needed them. I have snowshoed in it several times and have been thoroughly impressed with the breathabilty. I will also agree with the durability concerns, I wear my Arcteryx goretex shell when I can't be too delicate. I've noticed the event shell has more texture on the face fabric (less smooth then my goretex shells) and is more prone to pilling, especially under pack straps.
I think anyone looking to buy a WPB shell should see this chart:
kinda hard to read at first but basically the higher on the chart the more breathable it is, the flatter the line the more breathable they are in all conditions. The ones that start low and end high (goretex included) require you to work up a sweat before they start transporting moisture well. I can personally attest to the fact that mountain hardwear conduit membrane SUCKS. This chart is also why I never recomend proprietary membranes to people looking for budget rainshells, if you have to go cheap I tell people to get the Cabelas brand goretex, frogtoggs or army-surplus goretex.
in my experience army-surplus goretex is plenty breathable for the work I do, walking around outside lifting and moving things at realatively low exertion, but obviously hiking/snoeshowing is a whole differant animal.
another interesting chart:
this chart was made by a guy who put on each jacket and charged up the same hill at the same pace for each. the montane smock is eVent, and the obvious winner.
