Pros and Cons
Comprehensive port scanning of both TCP and UDP ports.
Clever 'interrogation' of services listening on open ports. It will use all sorts of techniques to try and work out what service is listening on a port, and potentially even version and host information, etc.
Very configurable. You can choose exactly what you want to scan for, limit to port ranges, protocols, IPs, etc.
Very scriptable. Being a command-line utility (check out Zenmap if you want a GUI), you can call it from your own scripts, automation pipelines, etc.

Pros and Cons
NMap provides a very fast and a very thorough network "sweep" that allows you to quickly map out exactly what's on your network.
NMap is highly configurable. The "canned" choices are very good in most instances, but using various switches and options, you can create a very specific scan and get exactly the results you're looking for.
NMap is easy to use. Even a new administrator will be able to use the graphical version (Zenmap) with efficiency right away.
