I like "gotten"and use it often. To my ears, it sounds gentler and less harsh then the staccato form, "got".
I don't think anyone has mentioned my absolutely most hated term which is probably used by at leat half the population every day : cuppa.
Aaaargh!! By all means ask me if I'd like some tea or if I want a cup of coffee but invite me to stay for a cuppa and I'll probably run away screaming! (No, I don't know why I dislike it so much and yes, I know it's illogical. But I loathe it with a passion😡)
