Definitely VSCode (or one of the many forks).

I also recommend combining it with Docker, the Remote Development extension, and Dev Containers, to keep your dev environment isolated from the rest of your operating system. That way you'll be able to easily install things you're not sure if you want to use, and cleanly rollback/remove them.

It'll also make life easier when (not if) you need to move your dev setup to another computer. Possibly even a completely different operating system.
