So you are saying to use a different tool to be fast but to use name for feature detection... Nmap is pretty darn fast if you disable feature detection!

No it isn't, nmap is ridiculously slow no matter what you do.
The only thing it does well is version detection, but you can do that too way faster.
If you specifically need nmaps version detection, sure use it. Otherwise you might be better off using masscan, it tends to do a pretty good job even with the default banner grabbing.
