For dildos, I like my Tantus Echo. It has a nice full head shaped like a guy's and plenty of ridges to stimulate the clitoris. The diameter ( 1 1/2" ) is not too girthy nor slim, which is quite suitable for most ladies. It is made of hypo-allergenic silicone which is one of the safest material for a dildo. It never fail to give me a good orgasm.
