I've never used XFX so I can't speak for them, but after the rebate it's the cheapest of the three, and they offer a lifetime warranty iirc, so you should be okay as long as you're not planning to overclock it into oblivion or otherwise do anything stupid that might void the warranty.
I'd avoid the Visiontek... it's expensive and it has the stock cooler, which means it'll probably sound like a Formula 1 car once you actually get into a game with it.
