Since at least before my birth, my family have always used an artificial tree (except for a couple of years when I lived with my mother and her partner, who had a real tree). Obviously, it saves a lot of money and still looks very nice, but the main thing I miss about a real tree is the smell. You just can't beat it. I think you can sprays to make the room smell of a real Christmas tree, but I've never come across one.
