"it might be faster" - when determining which nameserver address + family to
talk to, everybody does so on the (banded) historical RTT. The IPv6 address
might simply be faster.

Unlikely as this seems, I've seen an example of this, two AS's with adverse
relations, but an IPv6 tunnel provider that had a very good route via a
third AS.
