For me, probably either the Little Chroma/Steel or Form 6, if I can find one any time soon to inspect the quality and vibrations before purchasing.
I also lust after the turquoise Gigi, even though I have the Liv, which I love. They're very similar toys and I got the Liv instead of the Gigi because I thought i'd prefer it's shape, but alas, the curiosity hasn't ceased so I'll probably end up with both at some point or another.
I want a Chroma/Steel because of how quiet they are, and I like little toys and don't require super intense vibrations. I also love how sleek they look, particularly the Steel which I think is just plain sexy looking. Plus, I'm in the market for a waterproof toy.
Interested in the Form 6 again because I'm in the market for something waterproof, and I would also like something with a big more size than my lovely Liv. Most of the time I prefer toys to be smaller, more comparable to getting fingered than fucked, per se. Still, though, I'd like at least one thing with some more substantial length and girth. I've also considered the Elise for this but tend to think I'd prefer having the waterproof capabilities of the JJs. I've also been considering a few of the Jopens, and havent picked anything nor ruled them out. We shall see!
