What American English spelling can you not accept vs British or Australian?

American English spelling varies a bit from British and commonwealth English, particularly where we drop a U from some words, like “color” or “favorite.” For the most part, I’m not bothered by our Americanizations of most words. They look just fine. The one that frequently bothers me though is “mustache.” It looks so incomplete. It needs the O to become a much more dignified “moustache.”

Ironically, most of the British English spellings I dislike are the ones that have a random O, like “oestrogen” and “manoeuvre.” I know what the U adds in “colour,” but that O adds nothing.
