For modal editing there's also meow, god mode, and devil. Personally I quite dislike modal editing because of how you have to work very, very slowly and smash every key to make sure you don't accidentally do something like delete half the file, save, and quit; but I do have escape bound to god-local-mode for those rare times I need a long chain of chords. M-x some-command is usually good enough for me when I can't be bothered to memorise the chord, though.
