The two omissions that stuck out as glaring were 'Mash' and 'The Honeymooners', but you named some other shows that were just as obvious. (Personally, I think 'Barney Miller' is one of the best TV shows ever made, but there you go - - everybody has their own opinions.)
Any attempt at a "list" like this one absolutely needs to be separated by genre. Check out this thread from a few years ago:

Personally, I think 'Barney Miller' is one of the best TV shows ever made, but there you goAs would I. Barney Miller certainly deserves to be on the list. BTW, did I mention that Ron Glass, Detective Harris on Barney Miller, played "Shepherd Book," quite possibly the most interesting character on my favorite TV show of all time, "Firefly?"
