This is just my opinion but...
Unless you think she is VERY in love with trends, do not get her "the perfume of the week." It's so much sexier IMO and a more romantic touch, also IMO, if you get her something unique, unusual, less common. Make her feel special, a stand out from the crowd. That could be a niche scent, an atypical designer/department store choice, a vintage, or a classic.
I don't know the ones you listed there, except LL, which is hugely popular and may be a little too common. It's better than L though, which is way too common now, IMO, especially if you are looking for valentine's day. It may help if you tell us what she wears/likes now.
