I put 13,000 kms (8,000 miles) on my first ripsaw and replaced it with another ripsaw last season. I had a few lugs torn and track clips missing. Nothing I couldn't deal with, but with the Expert X drawing attention, I wanted the track to look good too!
I've never run studs, so I can't compare. I have friends who ran both and found the ripsaw hard on the arms for the first few rides because it grips better than a 1" with studs in our conditions (a little harder to turn). The advantage is because you don't spin as much, you're less likely to tear lugs.
If I bought a new one today, I'd consider the Ice ripper. Our trails are rarely icy, but you only need one icy spot to get you into trouble with a regular track.
