I've been using the open source TextMate. I have to say, it's one of the best free editors out there.
Folks started to give up on updates to TextMate years ago. I'm certainly glad that it's open now and being pushed forward, but that was only after lying stagnant for too long -- meanwhile Sublime Text propped up and pushed forward.
I've tried both ST and TM. TM is enough editor for me. I can do some pretty advanced things with it (like sending selected text to an external script) and it now has ongoing development and community support.
If you program in a mac, you might want to learn about 'Services', which is a way to do whatever you want with selected text in nearly any osx app.
If you said Chrysler was one of the best American car companies, and I said "They've got nothing on Toyota", then that would be a silly thing for me to say.
