Oh I believe IPv6 is faster but because of completely different reasons.
Modern faster connections more likely have IPv6 while old low-bandwidth
circuits may provide v4 only.
Some users may also use VPN which is almost always v4 only. Their VPN
may do funny routing, hair-pinning and similar behavior thus impacting
their performance.
