For a couple of decades, my go-to terminal-based editor has been JOE (Joe's Own Editor). [1]
JOE has everything I need — it's fast, it has syntax highlighting, multiple buffers, etc. Also, it uses the WordStar key bindings, which are the same bindings used by Turbo Pascal and the other Borland IDEs that I grew up with.
JOE is where I started my Unix editor journey, the Wordstar bindings were familiar coming from DOS and Borland tools. From there I went on to jed which also had Wordstar support and it gave me a taste for extensibility. Jed's native keybindings were based on Emacs though so I eventually arrived to the real deal and it has been Emacs ever since then. But also learned vi basics along the way of course. :)

But Micro looks great, too.
