Who is your Sitcom actor GOAT?

Is vs it someone who absolutely hit it out of the park in one role? Or someone who has had a long track record of success?

For me it would be Ted Danson, from one offs on Taxi and Laverne and Shirley, to all those years on Cheers, Becker, The Good Place, Mr Mayor and all those years on Curb as a fictionalized version of himself. He is hard to beat.
