Stuffing technically gets stuffed into the bird's cavity and baked at the same time as the bird itself. While dressing is baked in its own separate dish.
But most people I know use the terms interchangeably.
I'm not a fan of Stovetop stuffing, mainly because I was raised on my grandma's scratch-made cornbread dressing which is now my mom's main contribution. Anything else, just doesn't taste right, to me.
