Ranked in these QuestionsQuestion Ranking
Pro Sophisticated autocompletion
PyCharm includes sophisticated heuristics for determining what each variable type is and providing autocompletion suggestions for them.
Pro Version control integration
PyCharm has CVS, Git, Subversion and Mercurial integration.
Pro Excellent refactoring support
There are many refactoring options including renaming and changing signature across entire projects. It also includes the an ability to preview changes before committing and exclude anything unwanted.
Pro Excellent debugger
PyCharm can leverage run-time information when running your application with the built-in debugger to figure out what types can possibly be passed to which functions, etc.
Con Can sometimes become very slow, freeze, and become unresponsive
It becomes extremely frustrating when you have to wait for the text you've typed to appear in your editor. Furthermore, during these freezes the editor does not always queue what your're typing, so you might have to wait > 15 seconds before you can continue your editing. This quickly affects the concentration of a developer, causing flow interruption and general performance degradation.
