Sanford and Son, EASILY.
The Partridge Family is nothing more than a shittier version of the Brady Bunch. That's all it is. For some reason, I just could never get into this show, and it was always a lower man's Brady Bunch to me.
But Sanford and Son? Pure fucking gold. One of the greatest sitcoms, ever, with Fred Sanford being on the greatest, funniest characters in the history of television. If this guy didn't make you cry with laughter, then your sense of humor simply sucks. Seriously, unlike a lot of sitcoms from that day and age, Sanford and Son still holds up in entertainment and humor to this day. It's a great fucking show. Vote for it. If you don't, then you're racist.
