My father runs a big 6 man eskimo, and uses it a couple times a year. It's had its skirting tear unsolicited, but the company sent him a new one, and we haven't had any other problems with them. I'm more of a solo/run-and-gun type fisherman (at least as far as my feet can carry me), and believe it or not, I've been using a Tangkula 2 man pop up from Amazon, that I purchased when I was in college to save some money. It's still going strong after 5 years with a dozen or so uses a winter, no repairs needed. Moral of the story--if the Tangkula can last, it's my belief any name brand should be able to last. Even though we had the skirting problem with the eskimo, I'd go with one of those, as the company was good to work with when my father needed it.
