i do think Ms. is the best title bc it's gender neutral... but it's kind of annoying that the choices even exist in the first place. like that we even HAVE to pick between the three, that they all exist to specify our marital status.
whereas men, ONLY have "Mr" there's nothing that even exists to call them out on whether or not they are married. i've heard the term "master" for single men from my grandma, like that's equivalent to "miss" but never ever heard that used.
