I've watched three of those, to any great extent (Dexter, House and Big Bang Theory), with a few more on my potential watchlist (Battlestar Galactica and Watchmen stand out).
The rest I've either never heard of (in which case I have to wonder if they're my thing) or I have heard of and I'm pretty sure they're not my thing.
Still, 'best' artistic determinations I feel often go for pretentiousness over enjoyability, anyway, as any look at Oscars, Booker Prizes, Turner Prizes or the like will attest to.
The problems with comparing streaming services and broadcast TV notwithstanding, surely the 'best' shows are the ones with the largest audience?
