I've been using atom for a few weeks. On my low-power 12" MacBook, it is only slightly slower than sublime text. The only two tasks that are annoyingly slow are opening the editor or a new editor window. The barely noticeable lack of snappiness during editing is more than compensated for by the quality of the editor and its plugin ecosystem. I've also started using a ligature font for programming, which sublime doesn't support.
