What Electron-related problems have you had with VSCode? I've been using it as my primary for a few years now and it's been nothing but stellar. And that integration sounds incredibly cool.
Given your comments, I just installed it right now to try it out again. I like the built in terminal & git integration. Code search performance is excellent (w/ code hosted in WSL) due to this new client/server model... and there was no input lag in the editing window.
The only lag I noticed was in CTRL-P selector, but that's a small compromise given the client/server model solves the real time waster.
I think I'm going to try it out over the next few weeks :)
"source code editor" vs full fledged IDE
It doesn't make much sense to compare the two in general imho.
There's some VSCode extension that claims to mimic this but the fuzzy search seems much worse and it just doesn't quite work. Yes you can use the solargraph extension to sort of go to the def in vscode and it does all sorts of cool things, but I just never got into it.
It seems like a small thing but I just couldn't get over it, because I do it so often.
The main other difference is I much prefer the GitSavvy Sublime text extension to VSCode's built-in git handling. Particularly how I can see a summary of the commit I am making in GitSavvy whereas there doesn't seem to be a way to get all the file changes in one screen in VSC(though to be fair I didn't look around much for a way to do this, there probably is an option somewhere).
That being said if fuzzy search was working the same as in Sublime, I'd probably switch to Code.
