I've only had the cheddar and mozzarella. I didn't like the cheddar at all, but I love the mozzarella. I could just eat it by itself, but I generally put it on a pizza.
It does melt. I bake my pizza at 350 degrees, then when it is done or nearly done I take the pizza out, turn on the broiler and let that heat up for a minute, then stick the pizza back in for one or two minutes and the cheese melts beautifully.
