I think in the US it is really 90s dated and it has been used together with spelling variants
Briana,
Breanna,
Breana,
Bryana and
Bryanna.
The only one I like is
Briana pronounced bree-AH-na. It was used in The Faerie Queene so I consider it a classic.
Brianna looks trendy to me and the other spellings are even worse. I give
Brianna a 1 out of 10 but
Briana a 7 out of 10. I don't really care for
Bree. Maybe you also like Bria?
