Specs

Pros
Pro Blazingly fast
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.
Pro Excellent syntax highlighting
Kdevelop has very smart syntax and semantic syntax highlighting.

Pro Real-time static analysis
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.
Pro Best Vim bindings in an IDE
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.
Pro Integrated python debugger
Eric has a python debugger built-in.
Pro Good project management
Pro Integration with version control software
Integrates with various VCS.
Pro Integrated class browser
With Eric you can easily browse all classes in your current Python project and display the methods for a given class.
Cons
Con Works with no problems only on Linux
KDevelop is an IDE for the KDE platform. Even though it's cross-platform, it's mostly targeted at Linux systems and the versions for other operating systems are highly experimental.
Con Complex interface
Eric has a very complex UI. It overwhelms you with sections and windows and doesn't let you focus on code. Every tool is displayed on the top bars (there are 3) with no logical grouping or structure whatsoever.
Con Auto completion is not very good
The auto completion is not top-notch compared to other IDEs and text editors. In fact, many people recommend installing a third-party plugin to improve the auto completion found in Eric.
