I don't think there is one best type of prop. You may find on certain plane/engine combinations the majority of modelers choosing a specific prop, but what works best with one set up may not be the best on another. Even on a specific set up there will be different opinions on what is the best prop.

If you give a plane/engine combination and share what type of flying you want to do with it, I am sure prop suggestions will be offered. Don't expect everyone to agree.
