I can't say I love either one, but I could either one as a mn, perhaps. The "mew" sound is just a bit unattractive to my ears, I think.
Along the lines of Musetta/Musette, though, I did once work with a very sassy African-American woman named Muszedty, pron. mew-ZET-tee. People often pronounced like Musetta, but it was just so dang confusing. I asked her once about the spelling and she just rolled her eyes and said 'I don't have any idea what my mother was thinking, either.' :b
