Pros
Pro Flexible
It's property files allow for fine tweaks of its behavior, at a global or per language / project level. These textual settings might be confusing for those used to preference dialogs, but prove to be powerful, flexible, and fine grained.
Pro Lightweight
With less than 2 MB of binary on Windows, SciTE starts instantly. Plus, if you don't need all the config, syntax files, blah, there's a 678k standalone .exe version. Nothing is going to beat that for lightweight and start-up times. Stick it in a folder that is already on your PATH.
Pro Powerful
Based on the Scintilla source code editor, SciTE has some advanced features like rectangular editing, simple regular expression search and replace, code folding, etc. It allows the user to launch a compiler or interpreter, and it can also interpret the error messages, jumping at the location they point to.
Lua scripting is key to SciTE's power and flexibility. The Lua scripting language can be used to perform complex text transformations. It's relatively simple syntax and its large user-base makes it a great choice for a scripting feature.
Pro Built-in shell
The console window can show the result of ran commands (like build current file, reporting warnings, and errors), but also accept interactive shell commands.
Pro Portable
SciTE works on Windows and Linux, and it also has a commercial port on MacOS.
Pro Powerful syntax highlighting for numerous languages
Lexers providing folding and syntax highlighting are based on code, not on regular expressions. They support context, nesting, special rules, etc.
Pro Free (except on Mac) and open source
SciTE is written in C++, with lot of contributors, both to the core and to the numerous lexers.
Pro GUI
Has a simple graphical user interface
Pro Plugins allow for added functionality and customization
There are tons of plugins for productivity available in many different workflows, such as a dictation plugin, an encryption add-on, a whitespace remover, and more.

Pro Great UI
The UI is lean and minimal. Everything feels quite fast and it is easy to add custom shortcuts for doing things like compiling, deploying, or testing.
Pro Available on all systems that use Gnome
Gedit is the official text editor for Gnome and it's available wherever any version of Gnome is installed. With thousands of people using it daily and not even realizing it.
Cons
Con Hard to config
The configuration is mainly a file-based config, which can be unintuitive and difficult to use for new users.
Con Missing file browser
SciTE's greatest weakness is perhaps the file browser. It does not really have one, just a poor substitute which works a little bit like a terminal window with ls
or dir
commands to show the files in a directory.
Con Customization
No extensions, Themes.
Con Last line bug
Sometimes the last line of text is not visible.

Con Confusing interface
For example, finding anything in the settings menu is hard. Most other text editors use Edit->Preferences for managing settings but this is not the case for Gedit.
Con Faster than Atom but Slower than Geany
Not bad editor. Very similar to Geany, but Geany works faster and has more features.
Con Not a lot of features
Gedit is a text editor. Though it's simple and fast, it misses a lot of features, most notably auto-complete for several languages.
