REI all the way. They always have what I want, the salespeople are friendly, don't hound you, know what they're doing, and the prices are the best around. Plus the don't cater to gapers and they don't sell any North Face junk.
Seriously, though, what's wrong with marmot and FF? I like them both. Sure, they don't have as good a return policy as Returnable Equipment Inventory, but in my limited experience Marmot and FF are awesome.
