I've had the Rab Stretch Neo for a little over a year now and I'm very, very happy with it. It breathes noticeably better than my old Gore-Tex Pro Shell (that cost twice as much). The hood is excellent, moves well with your head and fits well over a helmet. The fabric feels nicer than regular hard shells too, it doesn't rustle like a crisp packet and has proved to be just as, if not more so, durable than any other hard shell I've used.
I've used this jacket for everything from winter mountaineering to mountain biking to backpacking in the southern Appalachian mountains in high heat and humidity.
My only very slight criticism would be that the pockets are of no real use as hand warmers, unless you want to wander around with your arms crossed.
You may also want to check out the Rab Myriad which is new for this Spring, it's another jacket using a slightly lighter weight of Neoshell and with a different pocket layout:
