I think that it is good that we have a choice in engines today. The wider the selection, the better for model boating. Competition among manufacturers and suppliers keeps the prices lower and the quality higher.
It was only a few years ago that manufacturers turned their attention from model boats to model cars. They made thousands of car engines and spent a lot less time developing engines for model boats. Now that the car demand has fallen, we are getting more and more boat engines available to us. Some manufacturers found themselves in a bind, then decided we weren't such a bad market after all.
To keep model boating active, we need a good selection of engines, a good supply of parts, and the most competitive prices. If we lose competition among the suppliers, model boating will lose.
As to what are the best engines, there are still lots of people winning races with silver head Piccos, MACs, Kalistratov, K&B, and other older engines. There are many good choices available for you.
