I mean, Atom is nice. The package management is all there and frequent updates are great, but...I don't write JS/HTML/CSS/PHP. I typically write Python, Go, Java, and heck even Prolog. Reading the changelog you can clearly see that they have a target audience, and I am not in it.
On the performance side (you knew it was coming!) I am mostly fine except for opening a project directory. I swear Atom has a coded in `sleep` whenever you try to open a file explorer. At first, I thought that this was a cute little quirk that would disappear after an update one day. But that update never came.
So I'll download Sublime again. Spend a morning to get it "just so" for, at the very least, Python and Go. I can easily see Sublime winning me back if I reinvest in it.
