I think the difference between chording and non-chording styles of input depends on the person. I have dyspraxia, which affects my fine motor control, so remembering and performing complex key sequences (such as emacs' keyboard shortcuts) is difficult for me, hell I have difficulty correctly typing ":qa:" properly to quit vim, I often type ":Qa" because I can't take my hand off the keyboard fast enough. I mistype so often, especially when I have little mnemonic data to go on.
Shift-Ctrl-End, Ctrl-X is two chords and 5 keystrokes, with <End> being off my normal typing position, even if I used that combination for years, I'll likely still get it wrong 1-2 times out of ten. I've been vim-ing for about 2 years now, I still get the movement keys wrong. I still type commands that I could bind to shortcut keys, or already have bindings (":redo") for example. I create ways to remember most keys, "i" for insert, "r" for replace, "s" for substitute, "d" for delete, "p" for paste, "g" for go (sometimes), "a" for append, "c" for cut. But I can't remember modifier keys normally, especially Ctrl and Alt, I've set most of the keyboard shortcuts on my window manager, I don't remember a lot of them, because they use <Mod4> (Windows key/Meta key). My point is, there's more to modal vs modeless than just how friendly it is, once I got over the initial hurdle, and forcibly trained myself to use h, j, k and l for motion (by disabling the arrow keys) I became far more productive in Vim than I did in any other editor, simply because I could use single key strokes for actions, I still press <Esc> just before doing any non-insert on text, even if I'm already in normal mode, and I still get things wrong, but I find it far easier to type "dwdwdwdw" to delete 4 words that to type <Ctrl>-<Shift>-<Right>,<Right>,<Right>,<Right>,<Del>, because its hard for me to hit keys if I have to move far. Pressing "dd" to delete a line is easier for me than doing <Home>,<Shift>-<End>,<Del>,<Del> because its a single key, if I got it once, then I can get it again. I don't care what editor you use, but I didn't pick mine simply because I wanted more hacker cred, I picked mine because it allows me to work around my disabilities. For the record, while I didn't track it, I estimate that I made about an average of 1 mistake per word typing this message, I mis-typed "track" 4 times in this sentence. -- James Miller
