I have both the Serenity and Roulette Lucky 13. If I had to pick one...I don't think I can. Both of these vibes get me off. They both have nice length and girth, which I insist on in my vibes. I think the Serenity is slightly girthier than the Lucky Roulette, but not by much. The Lucky Roulette gets me off easier strictly as a G-spot vibe because the tip is slightly more tapered and pointed than the Serenity. Don't get me wrong, the Serenity can get me there, too, but the rabbit is awkward to use because when I insert Serenity its full length to hit my G-spot, the rabbit seems like it's somewhere up near my belly button. But the Serenity is super pliable and you can bend the rabbit down to hit your clit. It can get a little tiresome, though, trying to keep it in the right position and thrust against your G-spot. The Lucky Roulette is a firmer vibe and not quite as flexible, but love the roulette wheel feature. Bottom line...if you want G-spot stimulation go with Lucky Roulette. Hope I've helped narrow it down for you. Let me know what you eventually decide. Good luck and enjoy!!!

I only can speak for the Naughtibod and the Lucky 13 and of the two my choice is the Lucky 13. The Naughtibod was one I thought I'd love because I'm a lover of music. unfortunately the music made the vibrations erratic and I didn't find the Naughtibod strong enough. Lucky 13 is a well made toy with a nice girth and the vibrations while not earthshaking are ample enough to get off on. I hope this proves helpful.

I've only got the Faith out of that bunch, but I'm happy with it. For me it works better during solo sex than with a partner and the orgasms it provides aren't necessarily mind blowing, but I don't find them lacking either. I hope that helps some?
