I'm confused by the variety of brands of toys on this list. If you're going the luxury route, where are the shiny new Lelo insignia's and Jimmyjane shenanigans?
I have the Mimi, Vr3, and had the Platinum Jack Rabbit. (It died on me after over two years of faithful service.) I can guarantee that these three are of awesome quality and have some super powerful vibrations. If I had to pick one of the three, it would be the Mimi.
Honestly, in terms of vibrators, I prefer the Fun Factory Yooo over any of those. It kicked pretty much every other vibe out of my collection, when I got it.
