I don't see that distinction, perhaps because tunnels count for almost
all of the IPv6 I do.

It depends which performance is counted - I find that IPv6 connectivity
tends to work more reliably than IPv4 most of the time (but that may just
be that most people advertising IPv6 make sure it works most of the time,
whereas IPv4 is just everybody, some conscientious, others not.

On straight bandwidth type of performance (byte per second) it varies
day to day - my IPv6 and IPv4 travel over different paths, sometimes one
is more congested, other times the other is.

But, the real issue, for most people, is that IPv6 by-passes NAT, and
IPv4 doesn't.   That's the one that matters, and for that reason alone
I'd always take IPv6 in preference to IPv4 any day, regardless of how
much slower it seemed.
