Overall they have mostly the same weaknesses than the NIST curves.
There are differences in detail, but it really doesn't justify
introducing a lot of variety in the ecosystem. But I have a pretty good
idea where that hearsay comes from, and I'm pretty sure it has little
to do with security.

The modern curves like Curve25519 and Curve448 avoid many of the
security pitfalls of older curves. If you want more secure curves look
at them and push standards forward so they can be used within X.509.
