I really do not like membrane softshells- especially with insulation as they are saunas. I might as well wear Gore-tex if I go that route (my Canadian made Gamma MX Hoody has been collecting dust for years).
Thus, the Patagonia Ascentionist appealed to me as the perfect jacket. After using it for two seasons, I have concluded:
good, slim fit
fabric is a perfect blend of fast drying, windproof, water-resistant and breathable
durable fabric (NOT true of the Ready Mix)
Hood does not fit my long neck correctly. While wearing a helmet, it is restrictive.
The hand pockets are placed incorrectly for a climbing jacket. They are too low and too small. If you wear a pack or harness, they are inaccessible.
The fabric is 2-way stretch, which is stiffer and more restrictive than Schoeller, Powershield, etc. (though better than Gore-tex)
Also, it appears that the jacket may be discontinued. The Guide Hoody has apparently replaced it, which is a heavier, stretchier jacket that (so long as you do not mind the weight) will perform equally well.
The Winter Sun jacket by Patagonia is the ultimate insulated climbing piece IMO- pockets are correctly placed, the fabric is the same as the Ascentionist, and the fleece is warm while also moving moisture.
I have no idea if Patagonia still carries these- they change their line up too often.
If you really want Powershield or the like, look at the Westcomb Skeena
