I have a setup that I maintain and I pop back to it every six months or so. There are probably three classes of things that end up turning me off.
1) VSCode is very UI heavy and doesn’t allow consistent keyboard and text navigation. I want my text editor to be text-based, and it slows me down to have different types of windows (some of which seem impossible to hide permanently) with inconsistent forms of navigation.
2) The terminal window is its own thing, even if you open it in an editor window, which is then ignored by anything that interacts with the terminal. This is more what I want but is very limited and immature:

The lack of an infrastructure like Emacs comint mode also means there’s no good text-based database mode either. I want the same navigation, search and editing functions in every single window I have to interact with.
3) Where analogues to Emacs modes exist, they are universally less featureful, often because of fundamental limitations of the VSCode extension API. REPLs do less and offer less programmability. Edamagit is a fine and welcome effort but not as good as Magit.
If people want an editor with a little bit of auto completion and some squiggly lines to tell them they’ve typed something wrong VSCode is great. I have many mostly happy VSCode users within my organisation. But I think every individual programmer, like every team, should have a regular little retrospectives with themselves. What work did I do today, what would have made it flow better? In every case, I can build that in Emacs, but it’s much more friction in VSCode. This is partly immaturity and partly the APIs not offering as much. Long term I’m rooting for VSCode because it’s snappy and has undeniable market share. But it’s never quite been there for me yet.
