Which font API?

I’ve been having some discussion about which font API’s to use, Cufon is rather old now, do people still use it?

Google fonts? I read something that @font-face is better now. So the question is really, which is the latest font API and why? Advantages, disadvantage?

Apologies if I did this in the wrong forum!

Google fonts is using css @font-face
You should be using CSS @font-face.
