Epcot definitely is, but it has more rides was my thinking and is a much bigger park. Epcot also has lots of little B-ticket type things like the circlevision shows or American Adventure, which i'd say based on scale and sets alone puts it at at least a high end C, if not a D.
Rumors kicking of them talking about a Seas and Imagination redo, but that still just keeps us even in attraction count. I wish they would use the expansion plot between The Land and Seas for something. Or any of the many plots in World Showcase.
