One possibility that I admit is very likely is that all my recipes need a mix of both, though certain ones may be weighed more to one or the other. Due to the mention of attribute requirements which damage progress and quality for being below them, I believe it's more important to ensure you have enough of what you need, rather than having a lot of what you need. So, what I generally do is look for a good amount of both types of craftmanship, with control thrown in where I can.
