As you know, mine had a Rotec radial. Looked pretty but had an appalling record of reliability. Three emergency landings in three years, constant problems despite regular maintenance, repair and returns to the manufacturer. I would not wish a Rotec on my worst enemy.
Is there a Rotec on record that has made 1000 hours? New builders love putting them in because of the look and the sound, but all too often they are swapped out if they need a functional and reliable aircraft to actually fly.
