I'm on ipv6 since 2 years and I am very happy.

I profit from NAT-less network, can connect to my home device from a VPS without thinking it's sitting behind 2 routers. No port forwarding needed, just connect and it works. Well, I guess I still need to enable connection to this device on a firewall, but that's obvious.

We really should move on from IPv4.

By the way, IPv6 also supports NAT if that's what you want. But using NAT in IPv6 is like saying "i want to have my own personal universe so I can put 2 Raspberry PIs in it".
