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

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.
Cons
Con Depends on Java
Because jEdit requires Java to be installed on the OS, it's not suitable for those who don't want Java.
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.
