Why do some prefer the door knob, and some the door handle?

Handles can be easier for some people to use/turn. It’s like a lever that can be much better if they have physical disabilities or aliments.

Door knobs – - – - round

Door handles – - “L” or “T” shaped easier to use for arthritics.

It seems door handles are pretty creative… I vote handles. Also I would find an artist
to make them for me.

You can hang a shirt on a round knob and it won’t get a funky wrinkle like a handle/lever type.
