I have used PyCharm daily since its early versions and have been mostly happy with it. When I think about it, it's actually the first IDE for any language I've kept using for longer than a couple of weeks. The best features for me include code navigation, run/test/debug, refactoring, inspections, keyboard-friendliness. It's also got a decent editor and built-in support for Sass and CoffeeScript. Btw, they also provide a free licence for open source development.

This is exactly what I say when people ask about pyCharm. I think i've tried a dozen IDEs and its the only one I stuck to. I've used it for a couple of years now for django and python development (and they've also just added first-class Flask support), plus I use it for front-end/javascript coding now too, I couldn't live without it now.
