Wearing a Gore-Tex shell over a down jacket for an extended period of time is a sure fire way to fill the down with moisture, which will reduce it's insulative qualities. That's why full Gore-Tex shells on down sleeping bags didn't work out so well. When layering, the more breathable layer (down) should go over the less breathable layer (Gore-Tex). That way moisture can work it's way out and not get trapped anywhere. If it's extremely cold, Gore-Tex is not required as it's not likely to rain or snow. The big puffy down suits that you see people wearing on Everest & Denali typically have a Dryloft shell, which is much more breathable than Gore-Tex, but still provides some protection from external moisture.
I've never worn anything made by Feathered Friends, but I know that their gear is highly regarded by climbers in Washington state. For comparison purposes, the Frontpoint Jacket is very similar to MEC's
Cygnus 700DL, which is a quality product as well (I have one).
