Kdevelop with kdev-python vs Spyder

PyCharm is amazing and easily the most feature option out there. But KDevelop is faster and has all the features needed for python develop. Opening new files, moving from file to file, code and syntax checks, everything happens instantly.
In the end the speed is what won me over to use KDevelop, when code is in my mind I don't want to wait on my IDE.

Kdevelop has very smart syntax and semantic syntax highlighting.

Kdevelop has a pretty powerful and sophisticated implementation of static analysis for Python. It's capable of pretty good type inference, tracking types and the expected groking of inheritance trees.

Most IDEs have very limited vim bindings, but KDevelop runs on the Kate editor. Kate is one of the most robust editors in the Linux world and is subsequently very functional. The Vim bindings are very close to complete with very few holes.

Spyder can plot graphs and provide the list of all variables.

Pylint integration enables to check the code for PEP8 style guide and detect errors.

Spyder's autocomplete features are made possible by a library called rope which gives Spyder powerful autocompletion.

Spyder (formerly Pydee) has support for all of the major operating platforms - Linux, Mac, and even Windows.

Aside from being an open sourced, actively developed IDE, vim key-binding support is also available. If you remember Pydee - this is it, albeit with a new name.
