I have my doubts that it has as comprehensive a library as nmap, for the -sV flag, where pattern matching occurs to determine a service name, and the .nse Lua language scripts for flags like -sC and —script

When I get time, I may check it out, one command I’ll use

find / -name .nse 2>/dev/null To find all Lua scripts for common service enumeration

“The modern port scanner” - maybe “The faster port scanner, but not necessarily the best in all cases”

Sometimes, older is better, given integrations and comprehensiveness of features developed out over time.
