I was using Atom for a long time and performance got better over time. I like to use OSS so Sublime was not an option for me.

Once I went back to vim, though, I was impressed again by its performance.

It's a pity that electron still has some trouble with performance. Slack, for example, does not make me happy. Visual Studio Code, on the other hand, is fast and is written using the same platform so there must be a way to do it right.
