I'd rank it 1) New Japan, 2) Dragon Gate, 3) DDT. However I have no idea what to make of IGF, they draw good crowds at big buildings but it seems like everyone who is into puro ignores them. Dragon Gate has a big audience but it's different from typical wrestling fans in Japan. A lot of women who are there for the pretty boys but also the company has been around long enough to have a dedicated fanbase.
Meltzer himself says the only reason Bryan won the Technical Award the last couple of years is because of his reputation. For those unaware, Wrestling Observer subscribers vote on the awards, I'm not sure if Meltzer himself votes. His opinions can definitely bend voting patterns a certain way but there are a few winners that he disagrees with every year.
