And when I press u I see a wall of text disappeared.

Maybe Vim let’s things go too far between undos.

I write a lot of text too, but I’ve never seen Emacs’s undo remove a whole wall of text that was typed by hand. If it was inserted from the kill-ring, sure.

Occasionally, it’ll undo a few more keystrokes than I’d prefer, but that’s rare. In that case, you can just undo the undo by pressing “C-g C-/”. And then remove only the text you wanted to get rid of.

“micro” (as listed in the poll) is a text editor which is unrelated to Emacs or Microemacs.
