Of all these I'd go with Liv, although I personally have the Mona.
To break it down: I'm not a fan of the Insignia line, so the Soraya doesn't tempt me at all. That plasticiness is not classy, I say. Also, the shape just seems wrong for a dual to me, I don't know. I know the clit arm is flexible, but holy widely spaced!
The Gigi is cute, but a) the shaft would be too short for me (I don't want to have to be inserting the silver part) and b) the shape isn't my favourite. I know a lot of people love it, but I have the Ella and it just didn't really rock my world. It's just okay.
The Ina - well, if you like super intense pressure on your clit, then maybe. Duals are also so finicky for fitting on any particular anatomy though, so I'm always a bit wary of them. I do like the shape of the internal shaft (which is why I got a Mona) but the dual aspect doesn't interest me.
I've wanted Soraya forever, but for a price like that, I'm not even comfortable purchasing. It just seems terribly over priced to me. However, Liv is another one that I would probably love! Price isnt as bad either.
I've heard good things about all of them, but I've also heard good things about Mona and G-ki. It all depends on peoples personal preference and how their anatomy is. What works for one might not work for another.
Gigi first and the Liv second; just depends on what your preference is and what you are looking for. All the LELO products are excellent! Great warrenty program. Good luck.
Ina. Hands down. I've never had a toy that even comes close to it. Especially all the cool settings that play around with the two motors. Seriously the Ina has made me a nicer person.
