I'm open for suggestions for a better one, but for me it uniquely combines open source (kind of) with ease of use and functionality / expandability. I used emacs for more than a decade and switched to VSCode (although I don't do coding as my primary activity anymore). Tried neovim, sublime, netbeans and webstorm and didn't convince me.
Support for weird stuff like integration with smart home (home assistant), better syntax highlighting / autocomplete for specific cases (like the home assistant mentioned above), better support for mixed fonts, database integration, more efficient use of screen real estate for side panels and less effort to add new languages in general (cdk, terraform, k8s with crd, go, etc), one click github copilot...
My current role needs me to deal with whatever the customer is using, so a whole lot of variability, custom resources and libraries, languages that I'm not super familiar with... It's just easier.
If it helps, I'm still running Arch, BTW. (but probably will go with just debian when my computer dies, whenever that will be).
