I'm curious what your metrics are for that conclusion.

By way of comparison, the new draft for the RFC covering storage protocol security (successor to RFC 3723) switches from 3DES to AES for clearly stated reasons, one of which is the fact that 64 bit blocks and large quantities of data don't go well together.  If you're dealing with small quantities of data, 3DES might still be good enough, but I still don't see an obvious reason to stick with a rather ancient cipher when a well-vetted replacement is available.
