I really wanted Atom to work. But in the end, it is just to damn slow, takes too much memory, and hogs on large files. Now, I find vscode to be very much what I need for javascript/typescript/html/css work.
That said, I am not 100% sold on it yet. The killer feature of Atom.io for me is that it is cross-platform. For most developers that shouldn't matter but have been working on some platform-agnostic web development tutorials and for that use case, there really isn't any valid alternative.
