Pro Vimtutor teaches the basics of Vim in 30 minutes
Vimtutor is an excellent interactive tutorial for people with no prior experience of Vim. It's bundled with Vim and takes about 30 minutes to complete.
Pro Everything is a mnemonic
Vim associates keys with words. For example, d
is for "delete" and w
is for "word". To perform an action you string together letters. Thus, to delete a word, press dw.
This way it's possible to abstract a large amount of functionality that Vim provides in an intuitive way.
Pro Enables effective keyboard-driven editing due to its modal nature
Interaction with Vim is centered around several modes. Each mode has a different purpose and switching between them changes behaviour and keybindings. There are 12 modes in total (six basic modes and six variations on basic modes) and four of them are used commonly.
Insert mode is for entering text. This mode most resembles traditional text entry in most editors.
Normal mode (the default) is entered by hitting ESC and converts all keybindings to center around movement within the file, search, pane selection, etc.
Command mode is entered by hitting ":" in Normal mode and allows you to execute Vim commands and scripts similar in fashion to a shell.
Visual mode is for selecting lines, blocks, and characters of code.
Modes allow separating concerns between various tasks and reusing keys for different kinds of functionality. As a result, the workflow becomes more efficient.

Cons
Con Slow when opening files with very long lines
A lot of very long lines can make MacVim take up to a minute to open, where a few other editors take only a few seconds to load the same file.
Con Only available on macOS
A decent text editor is available on all major platforms (macOS, Linux, Windows).
Con Difficult learning curve
MacVim after all is still Vim, and with that comes the complexity that Vim brings and the difficult learning curve that needs to be overcome.
Con Doesn't work in Mojave
The current version, with no issues. In fact, I've never had any issue with it with Mojave, so I assume when Mojave was released, aText was already up to date for it.
Con Frequent crashes in MacOS Sierra
aText crashes frequently, and the developer is unresponsive. Not clear if app is supported or under current development: last update was in 11/15; last post to aText Facebook page 10/15.
Con Long time no update
Seems to be abandoned.
