I tried atom, the only thing I liked about it was design and color scheme, the rest are superior in sublime text, so I just went ahead and created a theme/color scheme for sublime which matches atom (1). Atom is laggy, even basic file navigation using arrows can be slow sometimes (and I have a latest retine macbook pro).

But the biggest issue for me is a battery usage, it reduces my battery usage on RMBP15 by 2 hours compared to sublime text, I am mostly working from remote places and having a good battery usage is vital for me.
