it's very fast. Boots within 1s for me even for large projects.
Has a zillion extensions. Some of which you won't see in any other editor, or at least with the same quality. Like the powerful playwright integration for example.
LLMs can one-shot most small VSCode extensions when I need some niche functionality.
GitHub/Copilot integration is soo good I develop small features by speaking to my computer and even my phone because I can fire agents with voice instructions.
Jetbrains IDEs used to be my goto editors and before that neovim.
But it's so easy to customise and extend VSCode that I can't see myself going back.
