The advantages are very similar actually. The added ‘benefit’ or ‘disadvantage’ is dependent on your use case. If I regard my PGP key as the toehold to my online identity, having an ssh key tied to that identity is quite useful. Kind of neat to see the guy that signed the git commit is the same guy logging into the server, installing the software signed with the same pgp key. If your threat model needs to key your online identity somewhat anonymous, than a private key per server is likely the way to go. An encrypted ssh key is somewhere in the middle there.
