I use vim mainly. I'm not very good with it, but I use it because 1) I hate electron, and 2) I like modal (i.e. Vim) editing. There aren't very many non-Electron modal editors nowadays. Onivim looked promising but it's been abandoned so I've never gotten to try it. Lapce looks cool, but it's not mature yet.

(it also makes me feel ultra cool when other people see me programming )
