Hmm.. good question. Mine favs change everytime I get a new toy! Lol.
I love the twister vibe from pipe dream. Not sure the exact name of it. I also got the humming bird pleasure vibe from EF recently and I like it, but it's just for some reason not making it to my fav list. It's got every perfect details and function, but I guess I've not used it enough yet.
I got the Luscious Thrill-Her from another company last week and I absolutely LOVE that thing! It's definitely my fav at the moment. The Pipe Dream Twist vibe has always been a fav. I of course like my rabbit too, but don't use it often.
I also love the devilish fantasy strap on clit sting ray vibe from Doc Johnson. It will always be in my collection, even if I have to buy a new one. It is just one of the most amazing toys. It's really fun for a wild experience like wearing it under clothes, in the car, etc. Makes for a spicy foreplay time!
I have the Lady Lambada Vibe frm Twisted Miss. It's really unique and has a backbone, but it just seems to bend to easily, but is a great vibe!
