ReSharper has been a standard in the .NET world for well over a decade. If you're a C# developer and you don't use it, then you are at least familiar with it.
In the Python world, I believe that PyCharm has somewhere between 1/3 and 50% market share. That and VS Code are the two main games in town.
I'm not as well connected to other ecosystems, but I believe that RubyMine and PhpStorm are very prominent in the Ruby and PHP worlds.
I mean basically, in 2022 I would say that the vast majority of developers fall into one of 3 categories:
* They use a Jetbrains product.
* They use VS Code (I guess you can throw full-blown Visual Studio into this bucket as well).
* They use a plain text editor, instead of an IDE or more IDE-like tool.
