I think it would be fun/interesting to see some type of survey like that done. I think that just as there are subs who are fiestier and like to push their boundaries, there are going to be Doms that enjoy reminding their subs where the boundaries are and reinforcing their dominance. I think for some this is just part of the appeal. For other Doms, they will desire more compliance and there will be other subs that will crave more guidance/approval. I think there is a myriad of categories in between (and probably outside of this, too).
It would be interesting to see a survey done that would help both Doms and subs find where they land on that spectrum as I think finding a good match is key. For instance, if a more fiesty sub ended up with a Dom who wanted total compliance, or if a more compliant sub ended up with a Dom who wanted a little of a fight, it could cause problems in the relationship.
I also think it makes a difference whether you are a certain way all of the time. For me, in day to day life, my boyfriend wants me to be opinionated and have my own hobbies/interests. But when I'm specifically with him the dynamic changes. We're still very new in our relationship, and figuring out our particular dynamic, but knowing that he cares what I think and how I feel about things makes it a lot easier to trust him when he says things or does things that would infuriate me if it were anyone other than him.
