I've been using pyCharm for the last 2 years and its code completion has helped me code and learn at a much faster pace than other editors.

It offers code suggestions for any module that has been imported in addition to everything in the current script. Sublime and vim's code completion seem very primitive in comparison.

That said, I usually use the free Community Edition because it loads faster.

Emacs's elpy package is also great at auto-complete. I haven't used PyCharm myself but Emacs is more than enough. Also, most of my other programming are done in Emacs.
