I've found Hackage to just completely shit on PyPI in terms of:

- there's a good library - its relatively clear which 2 or 3 represent standard choices - its going to be well-tested including performance

The Haskell library ecosystem is a lot like the Python one with the bottom 80-90℅ lowest quality stuff sliced off. There's one of two things and they work. I was needing an HTTP2 client the other day, which a good one? Long pull in any language. Haskell has it of course.

You're right on data science stuff but that's everythinf: Julia and R get killed on libraries in data science. Lattner is working on that problem and he's not nailed it yet, its a "hard for Chris Lattner" problem.

One thing that might be throwing you off (it misled me at first) is that when a Haskell library has had very little work for a few years? That usually means its done, it changes when the world of foobar changes and only when the world of foobar changes.

There are exceptions to this, I wish effects and optics libraries had more consensus, but mostly there's a right one and it works great.
