Dunno if this topic has been done before..
Been watching some old All in the Family shows on the you tube recently, there's a lot of em, and I have decided Archie Bunker may be the best TV character ever. George Jefferson and Maude are good too.
I also really liked Larry David in Curb Your Enthusiasm. Is there a new season?
Another contender from days long gone would be Bob Newhart.
And for a totally different type, Spencer Reid from Criminal Minds.
