I'm not sure about performance. I do know that the open frame motors in MDC steamers were fairly high quality in their day. They at least are 5 pole motors and not the ancient 3 poles that early brass engine might have. You do have to realize that they will have a higher current draw when starting, so you have to pick decoders with a higher amperage rating. They also might not crawl like the modern skewed motors do.
