Visual Studio with the Python Tools extension vs Kdevelop with kdev-python

Has smart autocompletion based on variable types

Your Visual Studio Online account gives you a place to store your code, backlog, and other project data with no servers to deploy, configure, or manage.

In agile development teams one really needs features such as product backlogs where you can assign features to team mates and track their progress on them. VS provides a web based interface for you to track your team's complete progress on the project.

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.
