For me it would be 1989 Upper Deck and 1987 Topps.
1987 is when the hobby really just took off like crazy for the masses and the ‘89 Upper Deck set for all the reasons already mentioned
(although 1988 Score really was the baby step towards the UD set having been printed on slick board stock with player photos on front and back…but the set was hideous and had a “cheap” feel to it)
