I haven't used JetBrains but when I looked at editors a few years ago VSCode had an awful bug where if you had a Mac with a 4K external monitor it would flicker every time you typed a letter. It made VSCode functionally unusable for me. I use VSCode part time and overall find it less intuitive than the Nova UI/UX. Plus every time I have a problem Mike from Panic responds fairly promptly, and they've been responsive to some feature requests for things like debugging node inside Docker containers.
