I use C# more days than not. The comprehensive standard lib is impressively large and accomplished everything I need. Third-party libraries is a real pain point though. I haven't looked in sometime, but things like sane PDF libraries, reporting libraries, etc. were severely lacking when I needed them last. As much disdain as I have for Java, I think it is better in that regard.
>Python has a quite random collection of stuff, and it's often quite low quality and people don't use it anyway. I wouldn't say it is close to Go.
People who came into Python for ML and Data Science, and just care for their array and ML libs maybe.
But long time Pythonistas absolute use Python's standard library - and it's hardly "quite low quality". "Batteries Included" is one of the community slogans.

Even a decade ago (and more) the collections library in the Java standard lib was second to none. It's standard lib only got better since then (e.g. `HttpClient`).
I haven't used Java for a decade or so but as I recall its standard library was pretty bare bones (similar to Rust).
Apparently C# has a pretty comprehensive standard library but I've never used it.
