Code editing and workflow are really personal choices and subjective. I moved from IDE's to Sublime Text because of IDE slowness and annoyances. I made this move back when I did Java stuff and used Eclipse. I've tried VS Code a few times and just can't get into a flow, it feels slow. I find code suggestion popups to be annoying and usually never what I was going to type anyhow.
So I'd say try out text editors rather than IDES: Sublime (free to try out), vim, emacs, etc. They have enough options and plugins, etc. to make them really powerful.
Kinda funny that you have really good hardware and still found VS Code was slow at times. I imagine JetBrains costly subscription options are similar.
