I can't get used to Emacs (or Vim neither), they require too much keyboard interaction and they are aesthetically ugly
Once you get use to the keys and put a nice color scheme the efficiency that you gain is something out of pray, but i think that efficiency is no everyones call.
why are they 'aesthetically ugly'? do you mean they don't have windows with glossed borders?
I mean they lack in harmony IMHO, like KDE, which has ugly icons and button with not harmonious paddings
