Well, one feature is that the onion service design limits the surface area
to only that service. So you can't break in by e.g. sending malformed IP
packets that surprise the kernel. This feature isn't so helpful for huge
complicated websites that use php, since in that case the webserver is
the main vulnerability anyway, but it is pretty cool in the context of
an ssh server that is firewalled from all other access.

One benefit is that you're reducing load on the exit relays, so in theory
things can scale a lot better (you need folks to volunteer more non-exit
relays, but those are easier to get).

Another benefit is that you're no longer at the mercy of the Certificate
Authority mafia, and the mess which is the current CA model. (Alas when
it comes to site authentication we don't really replace the mess with
anything, so let's not get too carried away with how cool this benefit
is quite yet. :)

And there's actually lots more where that came from. Can I recommend our
32c3 talk for more info:
