Atom still sometimes freezes for me (on computer with high-end specs). Opening large text files also makes Atom freeze. The built in spotlight thing is slow for bigger projects (expected). The overall performance has definitely improved though.

I personally use Atom for lighter development and enjoy how easily accessible plugins are. Very easy to install support for lint tools/editorconfig/snippets/&tc.

It's better, but it's still not useable at a professional level. For example, a simple task such as CMD-D to create multiple cursors in a file. Sublime text screams through the file creating the cursors. Atom is like swimming in syrup. I wish Atom well, it's an amazing piece of software. But the developers chose a dev-stack that suited them instead of one that suited the end users of the software. So it will never take over the world as it could have. See also Discourse.

> Is it better?

Absolutely, yes.

I found it a little "bouncy" on first pass. It felt like there was an edge-of-perceptible lag when updating the display in response to keypresses. I tried switching to it again recently, and that's completely gone now. I guess it's just a tad on the slow side starting up, but everything else is really great, and I'm definitely sticking with it this time.

I've been using it as my main editor for a couple years now, and yes, it's getting better with every release.

Yes, it is quite a lot better. I just restarted using after two years pause.

Now I find that I open half my sessions in Atom, half in sublime.

My only frame of reference is visual studio... Atom is darn fast.
