I suppose that every engine brand has their very own fan club, but hey it's just like Ford versus Chev etc. I have owned several brands of engines including ASP that without any magic perform right out of the box as well as the high dollar engines like OS. The ASP 52 would be my choice and should serve you quite well in your trainer. With cash at a premium no need to buy a Benz when a Honda will do. Just my 0.02 cents.
