I've recently switched from Sublime Text to Atom. I've used Sublime for a few years and was very unimpressed when I first installed Atom 2 years ago. For a long time it remained slow and clunky, but recently not only did they improve performance significantly but also made the whole user experience much easier and pleasant.

I suggest taking a look at Atom before spending money on Sublime. The number of plugins and extension is just enormous. You might get surprised.
