emacs is a really bad comparison, given that it has million of functions and is infinitely customizable. It's slow performance has been subject of many jokes back in the 1970's [0] ("EMACS: Eight Megabytes And Constantly Swapping")

You should at least compare it to "nano" editor, or even better, it's predecessor "pico".
