Thank you for your question. Both fragrances are reproductions of Thierry Mugler's Angel and Angel Muse. Angel came out in 1992 while Angel Muse came out in 2016 so Muse would be a more modern scent. They share some similarities but are different fragrances. Online reviewers say that Angel Muse is easier to wear but the original Angel always has a strong following for those who like that kind of fragrance.
