I have watched both of these channels almost since they launched. GSN used to be a great channel for classic game shows, now Harvey Feud is on all the time, while I like it, I can't watch it for hours. GSN got rid of almost of its classics as well, the only ones left are Match Game, Card Sharks, and Pyramid, and even when they run those, they are sped up and are annoying as hell to watch.
Buzzr is much better. I know when they launched they didn't have a lot of episodes, but they have gotten better. They have classic Feud, Match Game Card Sharks, Tattletales, and many more. I am so glad Buzzr was made, they don't speed up the show, they don't have endless marathons (except on weekends). The Match Game and Family Feud marathons on Buzzr on weekends don't bother me as much because they are much better than Harvey Feud marathons EVERY DAY!
So what is your favorite, mine is Buzzr. GSN used to be good, but now it is complete crap. Which do you prefer?
