My absolute favorite is pure silicone. It's soft and body-safe and feels nice... the only thing I don't like is the little lint collections silicone toys like to gather. I also like glass and plastic - glass is smooth and has a nice, cool sensation when you start up, while plastic is lightweight and transfers vibration well (and it's cheap, so it's no heartbreak to replace).
I've also got a few external toys made of other materials, like TPR silicone, but I don't think I'd ever have any insertables like that. I'm considering a certain rubber toy, but I'm really not sure about it.
