I can talk all day about how great WireGuard is. Once installed it just disappears into the background doing its thing and you’ll never have to think about it again. No battery drain, no slowdown, no “disconnects”, no crashes, no issues. It’s rock solid. It has no concept of “connection”. It just forwards packets. There are no knobs and dials for encryption, there’s only 1 mode of operation (no downgrade attacks). With a pre-shared key set, one can rest assured that a broken key exchange wouldn’t be the end of the world.
