I got the bcurious because I have the layaspot, LOVE IT (ties with lelo's mia for my favorite toy currently) and reviews comparing the two said it was quieter, more powerful, it's waterproof so I could take it in the shower and wash it without worrying, and rechargeable is a MAJOR plus for me.
but it's so much harder than the layaspot, and I guess I'm more into broad vibrations than pinpoint because I don't get off as easily with it. I use the part of the bcurious that's at the very top (with the bottons, only underneath if that makes sense?) because the point of it compared with the hardness and shape literally feels like a big ol' beak on my clit. and beaks do not get me off. it is quieter than the layaspot by far but I just love my layaspot so much more since it doesn't have that point and it's softer.
I don't know how the bliss compares but I'd gladly shell out for a rechargeable layaspot if such an animal were to ever exist.
