Nmap: the best, free network scanning tool

Overall Satisfaction with Nmap
It's only being used by our IS department. Mainly for scanning of open ports on devices. Looking for possible security holes using Nmap's scripting engine.
- Open/Closed ports.
- OS detection.
- I would it say it's hard for new people using it as the there are too many switches.
- Better/faster udp scanning. I know that udp is best effort but something better would be great instead of waiting for timeouts.
- Positive return as it's open-source (free) on all OS's.
- If a person is not used of the command line there are a ton of front ends that make it point-and-click so the learning curve is good. That cuts down on time and manpower.
We have used these:
Angry IP Scanner
Advanced IP Scanner
Fing
Masscan
These apps are all Windows-based other than Masscan but they all work the same other than some of them are a paid product.
