Thanks for the cheat sheet link.
Looking at the cheat sheet you get a pretty good idea of the differences.
I've been using vi since the '90s. So, editing the command line is the same as editing a file. I don't have to think too much and my fingers spend more time on the keys.
With emacs you're using the Ctrl & Meta keys which to me aren't too as conveniently located as the alphanumeric keys. Just my 2¢
For command line editing, on the current command line,
Tap the escape key, then:
l (lower case L) will take you forward one letter at a time,
h will take you back one letter at a time,
w will jump forward to the next word
Note that it may stop at certain punctuation marks,
b will jump back a word,
k will take you to the previous command,
j the next command.
Note that the previous keys are all pretty close together.
Tapping the i key will put you into insert mode esc to exit.
x will delete the current character.
dw will delete the next word.
cw will allow you change the next word.
Once you get the hang of it. It becomes second nature.
Hope it helps.
