That's like asking me to pick my favorite child
.
For sheer sentiment, I'll go with "Cheers" because is started in the very early '80s. When it came on, I was in my early twenties. When it went off, I was in my early thirties. I got married and started out in the world during the run of that show. So there's a lot of nostalgia there for me.
But nostalgia aside, and everything being equal, I'm just as big a fan of "Seinfeld" as I am of "Cheers." Not to mention "Curb Your Enthusiasm."
They're also VERY different shows that worked for VERY different reasons
