It was the lag (and at the time, struggling to open "large" files) that stopped me giving it more than a cursory check a year or so ago. No idea if it's worth looking into again? Would be hard to beat sublimes snappiness doing almost any task.

Sublime is still faster.

But try VSCode. I do not notice any lag on the Mac.

I still prefer Emacs due to the maturity of its packages. But I have used VSCode for a month and I have no complaints about the performance.

There's been a massive amount of performance work in the last year. Definitely give it another try :) (disclaimer, on the Atom team)
