Pros

Pro Light and fast
Geany is very lightweight thanks to the smaller offering of features.

Pro Built-in plugin manager
Geany has a built-in plugin manager which can be used to install plugins and add new powerful features to the editor.

Pro Quick search on large files
In Geany you technically search once for a whole search query, unlike Gedit, where once you start typing, the file is searched for in accordance with each substring of what you're typing, all the while leading to terribly annoying lag.
Pro Cross platform
Geany is a cross platform editor, very similar to Notepad++ in Windows.
Pro Build in terminal
Press F5 and code will run without the need to switch between windows.
Pro Actively developed Free (as in freedom) Software
This software respects your freedom.
Pro Real syntax parsing (not just coloring)
Hence it is capable of showing the methods and inner classes of, e.g., a Java source file.

Pro Simple project management
Pro Native
It is a real app and not another frankenstein web/electron app. This means it runs great and doesn't extraordinary amounts of RAM.
Pro Options in the menu are easy to find
For example, there is an easy way to change the font and theme in the View menu. No need to search through several syntax styles like in Notepad++ just to be able to change the used font.
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.
Cons
Con Not very advanced
Although it has some IDE features, it is not as advanced as some other text editors that can be extended to contain IDE functionality.
Con Windows installer not digitally signed
Con Not many third-party plugins
Geany is not as popular as some other text editors with plugin support. As such it's understandable that it's missing lots of powerful plugins available in other editors.
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.
