I do have to say, that VS Code is entirely different, and the first time I played with it, I didn't realise it was using Electron.
It is really solidly engineered, with an insane amount of time and effort by great people working on the best of features for what an IDE needs, rather than the next shiny feature. (Scrolling, Time Travel Debugging, functional end points within to better allow for Vim and Emacs style integrations).
My upshot? Give it a chance.
This isn't something insane created by someone convinced Electron solves all their problems for them.
Its experts in TypeScript using what they know, inside and out, to make something deserving of the expert's attention.
The installer is 30ish MB, unliked the 200ish I've seen from a ton of Electron applications. gVim takes up the same amount of space on my system.
