I had a 2-stroke Yahama on the tail end of my Parker for 13-14 years. It had 1500 hours on it and was still running strong. No issues with it but it's age. I was getting ready to retire and could afford a new motor so I sprung for a 4-stroke.
As CaptBob said, quieter. Also, no oil usage with every trip. Not a big thing but...
It will really be a matter of personal opinion as to which is better. You have faithful followers of both engines. You can not go wrong with either.
