Glad to see it finally officially accepted. I've been using it on all my devices for over a year now and it's been rock solid. The ease of setup and initial connection speed alone blow any of the alternatives (that I'm aware of, at least) out of the water. Long may it continue!
The only place where it falls shorts is that it doesn't go through as easily as SSL/IPSec on restrictive networks like corporate firewalls, but maybe that will go away when it becomes more common (and hopefully adopted in enterprises).
I've honestly not had a lot of issues with that up until now. Real world it doesn't seem to be blocked by a whole lot of things, except where you only have port 80 and 443 anyway. I've actually seen it work in a lot of places I wouldn't have expected it to, like hotel wifi.
Actually there are workarounds to get Wireguard running over TCP and port 80/443 described here (like udp tunnel). I also wanted to check them out for very restrictive networks in the near future:
