Data point: I do real work in emacs (people pay me money for it). I haven't written any major emacs modes (use-package desired-feature) is it for me. I've looked at vs code (to get personal experience e.g., gitlens is nice though I mostly use magit plus several "feature" packages). Emacs is much better tool for me: I have an order of magnitude more notes than corresponding code (org-mode is life changing), say, 300 lines of notes per 30 lines of code.
I have many of my colleagues use vs code--expectedly, I don't see the "betterness." Ultimately, I don't care what tools do you use as long as the results are acceptable.
Though, I don't understand why someone would use less powerful tools long-term. Given your 20+ years experience, it is interesting to see some specific examples.
I was horrified for months. How did no one tell me how much better Emacs is over pretty much everything and especially VSCode?
In terms of brilliance, VSCode is a photon or two. Emacs is the Tarantula Nebula.
(I spent 20+ years with emacs, including writing one of the first popular HTML modes in 1993. We have better tools now!)
