What about vim?
They're ok when there are no alternatives like during SSH session but I've given up customizing after 10 years to make them act like any of the latter ones.
Why would I pay for IntelliJ if I could or someone had already made easy to use plugin to just make them act like modern editors?
Vim just has a lot less going on under the hood by default and is built for this.
In short, I guess I'm agreeing with your original post. Vim is just on another level when it comes to performance versus other editors so it's kind of unfair to pit them together.
That comment is _begging_ for a source. Whose general opinion?
