Unless you are moving gigabits of data, you won’t notice the difference the smaller header payload of ipv6 offers.
IPv6 headers are usually bigger anyway1, so the only advantage is more efficient routing (so infinitesimally better latency), but in my experience most routers only support IPv4 hw offload and not IPv6, so it’s only more efficient in theory.
I just like IPv6 because I get a whole /56 prefix to play with, and devices often randomise their host portion through the privacy extensions, meaning they use a new address each day or so.
1 IPv4 is usually ~20 bytes, but it can be up to 60 bytes if you stack a lot of options, IPv6 is only 40 bytes AFAIK.
