Have Continentals on our XC60 (CrossContact LX20) - 15k miles and no issues thus far. Quiet and smooth ride.
I had two sets on my Mazda3 that both went 55k miles. Shop said they work better with lighter vehicles, and that the ones you see on say a Mercedes sedan tended to wear out much faster than on my vehicle. I'm not sure if that holds up on SUVs as well - all I can say is I've been pleased with them thus far.
The Pirelli Scorpions the XC came with were not great, FWIW.
