I just checked the popularity stats for Vivienne and I was pretty shocked to see how quickly it's rising in popularity. Before seeing that, I would've said that it's not getting too popular at all because I have yet to hear of any babies with this name (besides Angelina Jolie's daughter). Regardless of its recent spike in popularity, I still like it well enough. I can't help but think that Juliette is a little bit pretentious sounding. Especially that spelling.
