Pro Mouse support
Scroll wheel works automatically. With mouse mode (F8) the cursor can be moved with a left-click to a desired position, and new cursors can be added with right clicks.
Pro No required dependencies
Pro Shows linting messages for Python code (requires flake8)
There's absolutely no need for ed when you have sed and ex.
Con Not a lot of features
While extremely fast and simple, Ed is simply not for programming for a long time because it lacks a lot of important features. It should be used instead for quick edits.
Con Not a persistent UI
You can only view portions of a file through search or regular expression commands. You cannot scan or scroll through a file using the available screen real-estate.
It's not too dissimilar in use to command-line tools (such as grep and sed) for editing a file. In fact, both grep and sed are based on how interaction is performed with Ed.
Con No region selection
Some selection features that are taken for granted in other editors are missing here. As they say in their documentation, if you want to copy and paste part of a line, you need to use the mouse to select it and copy with Ctrl + Shift + C.
