None if you only use email and the Web.
This is not true in the general case for web since IPv6 will not have to
go through the possibly multiple layers of NAT that increasingly have to
be used by Internet access providers due to the shortage of IPv4
addresses. Such so-called Carrier Grade NAT (CGNAT) setups are slower
than end-to-end connectivity.
On average, IPv6 conversations with top web servcies are about 2ms
faster than IPv4 and have been for more than a decade:

However, given what I know of Richard's setup in particular (a USB
connected cellular dongle), he specifically is not going to notice any
difference.
As I said in my reply to you, I effectively don't distinguish between it
and my old acoustic coupler ;}
Thanks,
Andy
