Atom is very nice. The Emacs of 2016.
(I'm a Vim user myself, but I feel like comparing Atom to Emacs is a big... optimistic. People keep complaining about how slow Atom is, how much memory it hogs up, etc. I think it needs at least a few more years of maturation before being able to call it "the Emacs of X")
Which is exactly what people have been saying decades ago about Emacs, aka "Eight Megabytes And Constantly Swapping".
