I think it might be useful to offer a rough benchmark of 3 degrees in the vertical subtype scheme rather than just two. I think there are roughly three that are somewhat commonly evident. Of course one instance is the relatively "pure" representative of the leading type. This would be an instance which suppresses the creative in acquiring knowledge in various cases actively. For instance, this is the introverted intuitive who allows intuitions to rule his life, and logic or ethics becomes more of an afterthought.
The next level is someone who is balanced enough that they have a consistent logical or ethical direction to their intuitions and can more freely deal with the creative's contents.
The final one is someone who gives high priority to both. Meaning sometimes it seems like intuition dominates and sometimes ethics. And you really need to infer indirectly which is leading and it's ambiguous if you can even say a definitive thing. This person almost looks like they have both as dominant types.
None of these is real, in that the real life is always an uncomfortable in-between.
