In my opinion there's no reason to stick to the "old school" / classic emacs controls. They're archaic at this point.

I am an experienced emacs user and I still use CUA mode, arrow keys, and I wrote a package which completely overhauls built-in "word jumping" commands (called bbww on melpa.)

You don't need to worry about upholding traditional emacs orthodoxy

Disagree with this just because it makes everything else easier. The more you stick to common key bindings, the more intuitive various packages will be. Eg navigating lines vs blocks in a magit diff block is C-n and N respectively. Copying a full hash is M-w. All these bindings are intuitive “overlays” on conventional bindings.

Emacs shines when packages combine to form a whole greater than the sum of its parts. Changing basic key bindings is the quickest way to vitiate that symbiosis.

Unfortunately.

And while they may be old school, traditional, and orthodox, they are by no means idiosyncratic. They’re widely supported: readline , bash, everywhere on macos, even modern browsers. Eg you can actually paste in bash: try killing something with C-w or C-k, and paste it back using C-y. Or transpose arguments using C-M-t. Navigate suggestions in Firefox using C-n and C-p. Bash even supports undo using C-/.

All to say: learning emacs movement keys pays off.
