No, it still fares very poorly when matched up against ST3 (or Textmate 2, or basically any high-quality native editor). It is slow slow slow, and has lots of little quirks which are clearly a result of the wacky way they decided to build a text editor.

BUT.... it is way, way better than it used to be. I keep it installed and use it from time to time, to let it update itself and see how it has grown.

It clearly has momentum, and computers clearly are getting faster... probably one day the slowness of it won't matter. But it still matters today -- Atom is noticeably slow on the fastest Mac notebook you can currently buy.

I would say that it's at 90+ percent feature parity with ST3; the only real downside is that the package/extension ecosystem is nowhere near as mature as with ST3 right now, but that looks like it is changing very quickly. In addition, ST3 is closed source vs. Atom is open source, and that alone could be a good reason for a number of people to switch.

My recommendation is to give Atom a chance, see if it fits into your workflow (whether it has native support for the languages/frameworks you work in, or if packages exist). If it works out, then you have a viable alternative to ST3 :)

I only keep using ST because of:

As a paying user of Sublime Text 3, I finally jumped on the Atom bandwagon a few months ago and have overall been pretty happy.

It's certainly a slower editor - I have found that opening it, creating a new window, and quitting all take more time than I would like. However, I have stuck it out primarily for two reasons:

1. It's far more extensible. Sublime Text has a thriving package ecosystem, but the limitations of the extension API show up in lots of little places. Atom being browser-based comes with its downsides, but it also allows flexibility that Sublime could only dream of.

2. It's open source. Sublime Text is a great editor, but it's closed source, maintained by a single guy, and updates have slowed to a crawl. It's not something I ever felt 100% comfortable with relying on as part of my day-in-day-out workflow.

At least worth trying. I like atom a lot but it's still noticeably slower than ST3 on my late 2011 Macbook, even with SSD.

Atom is nice but much slower than ST3. It takes 30 seconds to open a file while ST3 almost instantly loads. It's not worth switching from Sublime.

I prefer Atom, although I never was quite a ST3 super-user.

The speed issues are all but gone imho (start-up is a bit slow, but I have it open almost all the time so I hardly notice).

The main reason I switched was because Atom is FOSS, and that always bothered me about ST3. It's also very easy to hack on, which is nice as well.

I'm not a heavy plugin user, so I don't get a lot of the power-user benefits of ST, but the git integration alone has been worth switching. If you're editing a file under source control, it keeps track of changed segments (and files) out of the box. Nice, simple tool that's been really handy even though I only switched last week.

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.

If you have a setup that works for you, probably not. Atom's main advantage is that it's in a DOM environment and people could do neat things with it but at the moment the efforts have gone into putting it roughly at feature parity with ST3.

Both are good editors, I haven't tried Atom in about a year. Try it and then report back.

I switched from Atom back to ST3 a month ago.
