I keep trying Atom, but performance is killing it. Especially multiple cursor support. If you try changing a token that appears several hundred times, pretty much impossible.
In brackets, it is painfully useable doing the same, but in sublime you can't even tell you are editing hundreds of lines, it is just as fast as editing a single line.
Javascript is now fast enough, but the DOM seems to be the roadblock. I'm hoping one of these editors will finally make an innovative leap like react-native did on mobile but on the desktop. Skip the DOM and use canvas or native widgets. We should then have something mostly on par with other editors in terms of performance.
