Most of the others just say "better" instead of saying what the desired sort of theory actually does.

Actually, it's precisely for this reason that "reflexive" doesn't work for what I originally wanted: I wanted to use a word to denote TDT, UDT, ADT, etc, not in terms of how they work but in terms of satisfying the five conditions, the most important of which is that they out-perform CDT. How a decision theory works is a secondary consideration to how well it works.
