Is Teflon the best?

Are dishes and cookware that are made using the Teflon material the best when it comes to cooking? I mean, sure, they don't make the food stick, but what are the other advantages of using them?

I don't know about advantages, other than the obvious one. But I have heard of risks - again the most talked about one is that of toxins being released when the pan is heated. Of course, this is said to be true of other nonstick materials as well.
