I prefer
Madeleine because I don't like the pronunciation confusion with
Madeline, and I don't think I've ever met anyone who pronounces it with the EYE ending.
I think overall I actually prefer the American spelling
Madelyn! I wouldn't consider it "kre8ive," though there was a time when I would have. The "leine" thing doesn't really exist in English, and -lyn makes more sense.
