I'd like to add that it gives you a secure tunnel, not necessarily tcp
over tcp, between two endpoints. I can't do that with telnet (eg,
when someone connects to port N on machine X, initiate a secure
connection to port M on machine Y). This simple feature is very nice
and solves a large class of problems.
I also like the fact that I can do all my interactive (slogin) and
non-interactive (ssh and scp) over 1 tcp port. This makes configuring
firewalls easy. For telnet I need some other file transfer protocol.
ftp is the only other one available, and it needs special hacks to
cope with firewalls (and vice versa).
Finally, with ssh I can set things up so that it forces encryption and
strong authentication. I don't believe that the current telnet is so
configuratble (I could be wrong).
