There was an article sometime in the last few months in Aviation Consumer (
www.aviationconsumer.com) regarding ratings of overhaul shops.
Personally, I would lean towards an overhaul from a reputable shop if I had first or second run engines and planned to keep the plane for a while.
If I was getting ready to sell, or the engines had already been through overhaul a couple of times, I would go with a factory reman since the market (perhaps mistakenly?) values it more highly.
