If I had to pick one, probably Burberry. I mostly buy from outlet stores cause I can't afford full price.
You must be fairly well off if you buy Mammut, I'm poor so I have to make do with Haglofs.
I work a lot and I know the brand pretty good. I have a fleece jacket that is about 6 years old but looks new. I will skimp on other crap to buy Mammut.
