It depends on a country. I was at places where IPv4 is the default choice. I also visited countries where IPv6 is a standard practice. As a consumer, you really do not see much difference, IPv6 works surprisingly well if not better than IPv4.

Most US mobile carriers are IPv6-first or IPv6-only with big NAT64 gateways. One of those countries these days is the consumer parts of the US.
