I like
Vivian because it's so snappy and purple. It's a bit dark and mystical, too. But I still have that initial reaction to avoid it because it used to be SO BtN-trendy. :P I think it will continue to rise in popularity. It has that sharp sound, has been used by celebrities, and I think Vs seem like the cool thing.
My favorite combo with it is
Tesni Vivian, which if you flip around still sounds nice.
