Each IDE has its strengths, so it’s worth trying a few to find the one that best fits your workflow and project needs.
For info I actually use VSCode, for a couple of reasons – I also use PlatformIO in Visual Studio and also use it for some of the other sites that I contribute for JavaScript and Python
Its free and does the job but I recommend people try any free trial or download and simply try the IDE
