1-A+ and High 1-A would stay effectively the same. The former would be for an infinite hierarchy of qualitative superiorities. The latter would be for characters who are above the "quality" defining the lower hierarchy altogether, while still working on their own, higher form of qualitative superiority. For example, in Marvel Comics, the omniverse has an infinite hierarchy of dreams-within-dreams in itself, and above that, then, is the Outside, which transcends all forms of reality and dream and yet nevertheless still has its own hierarchy that works on something else entirely.
