I use it pretty interchangeably with ST3 since most of the keybindings are the same. For Rails, JS and general web work, it's pretty nice. The Atom Linter plugin is nicer than at the Sublime linters I've tried. I've been on it from day one and have encountered a number of bugs, but I do prefer its settings pane and ability to reskin the entire ui easily, the ability to quickly tweak themes and plugins with just html, css and JS and the fairly quick pace of development. I like that they're curating an official package manager with an update UI and an official repo instead of it being 3rd party bolted on functionality. Remapping keys is easier and profiling a slow/problem plugin is doable without resorting to trial and error.

I do wish there was a good way to resize split panes though. And the file size limit sucks when wanting to view logs. Their vim mode is still not emersive (my only comparison are evil-mode, which does a damn fine job, and ST Vintage mode, which is... ok).

It's still new, I'm willing to forgive growing pains and I think it could easily overtake ST eventually, given that it's fully open source, is making faster progress, is free, and offers a whole lot of feature parity. Speed has never really been a problem for me and my codebases, but i can imagine that the web stack its built on could be a source of problems in some scenarios.

I used it a month or two ago and found it unusably slow but recently gave it another shot after they released an update and now it's pretty much on par with Sublime on my system. It might be worth you giving it another go.

I set myself a target to use it for a day, but it slowed me down far too much and I ditched it within three hours. I'm going to try again when there is more stability and speed.

I am. I was heavily using Sublime but switched over for a trial period to see if I liked it. Overall I'm quite happy with it; it's incredibly snappy for me (almost as snappy as Sublime) but it's start-up time is a bit slower.

So for now I'll probably keep using it but on some larger files it can become slower much quicker than Sublime or others. Fortunately I practically never work with large files so it's not that big of a deal.

I switched to Sublime from Vim because it looked prettier, but Atom looks better out the box. Also, Sublime barely moves on my 09 tiny macbook air, while Atom performs well.

On the 2014 iMac, slowdowns on big files I barely noticed, what I don't like is that if you have the editor open forever, it starts moaning like a dying whale, regardless of the beefiness of your rig.

>I switched to Sublime from Vim because it looked prettier

I find this to be a very curious reason to switch from Vim... were you a very experienced Vim user? Ever give MacVim a shot for the different color schemes? Don't get me wrong, I like my editor to look nice also, but Sublime isn't exactly a prettier version of Vim - they have very different strengths and weaknesses.

Yeah, about 5 years or so. I'm using the vim plugins for both atom and sublime. I liked the minimap, and the default font. More importantly, it was hard for teamates to get used to when doing pair programming.

Also, it's not really that different, save for the modal editing stuff. Anything else there is either a plugin, or a clone, or better stuff.

I'm used to heavyweight IDEs like Eclipse, so it's pretty snappy by my standards.
