Comes down to preference. I still use sublime for opening really large files. But otherwise i stick with Atom. I've found when using linters, typescript compile checking and such Atom is just better. The notifications built in and such are great, where as the bottom bar for listing that kind of stuff in sublime feels archaic.
The consensus seems to be that Atom is still much slower than ST3; I'm still on ST2, and I find it terrible for opening large files and mostly resort to Emacs for that sort of task (and anything involving search and replace with regular expressions on even moderately-sized files). Is ST3 markedly faster than ST2 and generally worth upgrading to now?
(I've held off upgrading because I've always been in the middle of a project... but I'm now realising that I really am just always in the middle of a project, so I might as well just get it over with.)
