Frameworks support, autocomplete HTML/CSS/JS, templates

Pycharm supports SQLlite, PostgresQL, Mysql, etc out of the box and is integrated very nicely with Pycharm. Making database modifications could never have been easier as changing a cell value and committing the changes straight from pycharm.

PyCharm has amazing code navigation implementations. It supports both goto symbol and goto declaration. The former finds classes, variables, functions, etc by name. While the latter is used by moving the cursor on top of a symbol and by using the mouse or a keyboard combination it finds the declaration of that symbol and takes you there.

Both of these features are extremely helpful when consulting large code-bases and when trying to understand an API written by someone else.

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.

PyCharm has two types of autocompletion: structural completion and word expansion.

Structural autocompletion makes predictions based on its understanding of Python and JavaScript objects, while the latter tries to predict the word currently being typed based on previously typed words. Word expansion also works in comments and docstrings and it's similar to vim's omnicompletion.

Both types of autocompletion work extremely well, have little to no problems and are quite fast even when loading suggestions on the go.

PyCharm has CVS, Git, Subversion and Mercurial integration.
