That's an insightful question. I would say that the user-experience is simpler and the automation is richer, look at inletsctl and inlets-operator for instance and the Kubernetes service discovery. Inlets OSS can also multiplex sites and is more comparable to Argo Tunnels from Cloudflare or Ngrok than ssh.
Because inletsctl/operator uses cloudinit it is slightly easier to automate than setting up authorised ssh keys and then managing those, but the end result of local traffic appearing somewhere else is the same.
