The actual critic roundups tell as much a story of FX's dominance of prestige TV as HBO's. And if you want a popular opinion instead, the ratings have a much bleaker story about HBO.
While I think Netflix does just fine as an original producer lined up against HBO, it's not a central part of my argument that they're better than HBO. My core argument is that HBO doesn't host enough prestige series for it to command a premium over all the other series available across other platforms.
A ranking based on how many paid-for critics are talking about a TV show? Huh? That's like saying "this startup is better than another because they've gotten more press on TechCrunch/Wired/WSJ/etc". IMDB is imperfect, but it's a better proxy for what consumers enjoy.
If you're looking for what consumers enjoy, look at the ratings, where HBO also does not fare especially well.
