Pros
Pro First-class mouse support
Slap supports mouse keybindings even though it works inside the terminal and also through SSH.
Pro Uses desktop-like keybindings
Slap features configurable keybindings (Ctrl+S, Ctrl+Z, etc).
Pro Great terminal interface
Pro Native multi cursor editing on the command line
Multiple cursors & column selection allow versatile ways of editing.
Pro Low learning curve

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)
Cons
Con Requires node.js
Slap is written in JavaScript and it requires something to interpret it in a local machine. That something is node.js, but for people who don't need node, it would be a hindrance and an overkill to install node just to use a simple text editor. Furthermore, it can only be used remotely if the remote machine has node installed.
Con CLI only
Slap only runs through the terminal.
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.
