Are retro TV shows from the 60's 70's and 80's better compared to today's sitcoms?

Just wondering if all the retro sitcoms like Happy Days, Mork and Mindy, Dukes of Hazzard, the A Team, Sim Million Dollar Man, Wonder Women, Greatest American Hero, The Fall Guy, Airwolf, Laverne and Shirley, Minder, Get Smart, Highway to Heaven, Magnum P.I, MacGyver, Quantum Leap, Grizzly Adams, Lassie, Flipper,Hawaii 5 O, The Outer Limits, Charlies Angels, Miami Vice, The Twighlight Zone, The Beachcombers, The Littlest Hobo, The Cosby Show, Welcome back Kotter, Brady Bunch, Family Ties,Daniel Boone, Bj and the Bear, The Time Tunnel, The Waltons, The Ghost of Mrs Muir, Mash, The Bionic Women. Were they better than today's TV sitcoms? I think people are watching them more than ever because they are disillusioned with the amount of garbage that on TV these days.Some people say they are outdated, well I still find Mork and Mindy's humor quite funny. I think the tide is turning. Like old school music the old school (sitcoms) will never be forgotten.
