From memory, so I'm probably wrong, but: I thought the bona fides for Curve25519's design was that it demonstrated clear engineering reasons for all its choices, and Bernstein's issue with other curves was that NUMS constants (like pi, e, etc) were manipulable in the sense that you could take permutations of them --- the (silly) B4D455 paper.
