I've had Vietnamese cinnamon (Penzey's distributed in US) and gave it to a friend ho appreciated it. It would have changed the flavor significantly in my baking which is where I use it most.
Vietnamese cinnamon is closer to cassia than to true cinnamon. Sri Lankan cinnamon is probably the best for baking, if you can find it.
