Atom now has its own installer (no more Chocolatey on Windows for example), has an update manager for itself and its themes and plugins, and has gotten more stable as of late.

However... It is slower than SublimeText 3, noticeably slower. I tend to keep applications open for weeks, using "sleep" mode overnight, and Atom still tends to crash after several hours. This means I don't use it for real work, yet.

While Atom does indeed keep getting better, ST3 is becoming more and more frustrating as package updates now have a tendency to vomit errors when ST3 starts up. It complains about not being able to load a config file for the package (like Rust mode or the Cobalt theme). When this happens, ST3 disables the package, but a restart will clear the hiccups.

SublimeText is clearly the better editor, yet there has been no progress on the beta. Worse, this has caused a division of effort among third party providers who have to support ST2 and ST3, with no clear end in sight for an ST3 stable release.
