What IDE could I use that:
1) Doesn't require me to switch to vim or emacs key bindings 2) Has strong auto completion for web development 3) Is more performant than electron style applications
I used Atom when it first came out and loved it, despite people's constant complaints about it crashing and being unstable. It just ran so smooth for me.
Then I moved VS Code so I'd be using the same editor for my personal development that I used at work. About a year ago (3 or 4 since I moved from Atom) I decided to give Atom another try, and was miserable. It crashed constantly and when it didn't crash it would run at a snail's pace.
I've installed VS code on multiple machines and haven't had any issues, despite both Atom and VS Code are Electron apps.
I have noticed that IDE's based on Scintilla are very responsive. Much better than ones based on Java frameworks and vastly faster than VSCode. The memory usage is much smaller. Current medium sized project I have open is using 45mb of memory.
A suggestion is to do the brain dead thing I did and look at the lists of IDE's on Wikipedia and try the ones that might work for you.
