I think it is stuffing if you cram it in the turkey.
And dressing if you bake, fix on stove top, or in microwave.
I was always asked to make my dressing in a pan and have some Krispy on top. I believe ppl always loved eating my dressing mainly because I didn't use a lot of seasoning. What seasoning I did use was fresh.
I don't care for turkey and therefore haven't baked or stuff one for years. There is absolutely no sense in it.
