I'd say the Gryphon is microscopically weaker than High Priestess (FAN), Minister (WDN), or Jumping General (DWAF). The (0, 3) move is longer, so it is more likely to be off the edge of the board, lowering its mobility slightly. And, because it changes color with every move, it cannot triangulate.
I'd have to give the other pieces more thought ...
