I remember in the 80s the debate was Beta or VHS? I could never see the difference, but Beta was supposed to be the better of the two. My uncle swore that he could tell the difference, but I just never did see it. I can’t speak about Blu-Ray, as I have no first hand experience with them.
Beta WAS better than VHS especially when recorded in the slowest speed. I know because I owned a betamax.
