I switched from Emacs to VS Code some years ago after being a hardcore Emacs user for many years. For me it was customization fatigue. Just an endless accumulation of Emacs Lisp one liners and functions that I have no use for outside of Emacs. In comparison, I don't even know where my VS Code dotfiles are. I don't need it to be set up with my customizations, I just use it out of the box and add extensions when I need to.
