I have them on my plane, but they were there from the previous owner. I can't do any direct comparisons to know what the benefits are. Are they slightly quieter, smoother, better climb? Yeah probably.
One thing I do know, is that they are relatively fragile. I've had to send the props out for repairs twice. An isolated rock chip can require repair. Repairs are relatively easy on the composites but it does mean removing the props and sending them out to a certified shop. For this reason, I would never land on a gravel strip with mine; the chance of the rear prop taking a rock chip is too great.
