Superscan4 is good, assuming you really mean a port scanner only, and not a vulnerability scanner, like Nessus.

Also depends on your host OS. Nmap is good:

Well ive got to say Nmap is the grand daddy of port scanners. It can do basically everything. However it is not as user friendly as many of the gui scanners available.

If you don't like SuperScan 4 then try SuperScan 3. It has a better user interface. Also, I still vote netcat as the best--but not the easiest to use--TCP/IP network port tester. It's currently #4 on the Top 100 Network Security Tools at insecure.org.
