iirc spiped uses TLS/OpenSSL for securing the connection, the symmetric key avoids the key-exchange and worrying about certificates, and therefore is better capable of efficiently using the connection than SSH by itself.
Because it's much simpler it's also a good way to expose a system to the internet, although Wireguard with a PSK is a very similar and possibly superior solution.
