I too think A, B, and C are all relatively and can't be defined by pricing or rigid definitions of context. Heck, you can even have A splash vs B splash on the same title and A panel page vs. B panel page on the same title.
Here is a practical example, since the bulk of my collection is probably B (I suppose by definition very few people have collections that are mostly A).
Kevin Maguire One Punch page (not mine) - A - CAF Link
The page after the one punch page (mine), still lots of great content, but only a B relative to the one punch page - CAF Link
