Cardboard Connection put up a nice post/gallery for the 60 years of Topps
Personal favorites are:
1978 Topps: Love the simple design and team name script. And the 4 quadrant rookie cards were brilliant.
1981 Topps: for some reason, I never can forget these hats and it was, for me, just a memorable design.
1987 Topps: Seems to be a common favorite. The wood paneling and the massive rookie collection it had.
