I switched from Sublime Text and completely happy with WebStorm’s performance. Not to mention that the set of features is way better.

Refactoring feature saves me a lot of time every single day. Autocompletion is great, especially with statically-typed languages.

One of my must-have plugins is IdeaVim. I’m not a power vim-user but navigation and window-management with vim-shortcuts are much faster and, somehow, intuitive for me).

I work all the time in the “Distraction Free” mode, so I see only my code and everything else is called with shortcuts.

My font for a couple of years already is Source Code Pro
