Duckdns/wireguard/... Which one do you prefer and why?

Hi everyone

So, that's a 2 in 1 post. First a more general question then looking for advice for a friend.

• What is your preferred way to access HA from outside (and why)?

• a friend of mine use duckdns and I often read (recently) that some people are having issue with it. Is wireguard a better way or another solution that is not too techy to deal with?
