(preface: I'm talking about personal/homelab experience and usage)

I know this is not going to be popular, however: I still use plain and simple OpenVPN and frankly i've been very happy. It can do both ipv4 and ipv6 and with some more work also layer-2 bridging.

Yeah performance is lower in theory but frankly that has never been the issue for me.

I'm pretty much always bottlenecked by bandwidth rather than cpu time.
