Npm has more abundance of good packages. They are typically better documented and easier to get started with, sadly :(.
JVM has some really great stuff - things which are lightyears ahead of what is there in NPM. Much of which started as university projects, as Java is popular at schools.
I wish JVM developers took a hint from others and started making very easy and fun documentation, but have no high hopes.
