I suspect I am going to be running dual stack for at least the next decade, IPv4 switch off feels very far away. I don't think there is much advantage or disadvantage to running IPv4 compared to translation. The current internet doesn't feel ready. I have had less issues with IPv6 this year compared to last so there has been some progress but I am still getting fallbacks to IPv4, some companies don't seem to care much about IPv6 outages currently.
