I've not put a set on yet simply because I've got a stock of half worn PR2's I'm using up. However, I will run a set to compare. I don't know anyone that has gone through a set far enough to gauge how well they will last. I plan on running PR2s in the IBR simply becuase I know how they handle. I plan on changing the rear at a checkpoint anyway so longevity is not a concern and I know a PR2 front will go the distance.
I don't see here where they actually compare the different compounds but I'm told the center compound on the PR3 is harder and the outside is softer. The guys at simply sport bikes are relaying info from Michelin that says the PR3's should generally last slightly longer than the PR2s.
