I have looked at a couple of blogger/vloggers and find their charmed life swanning around on freebies or credit card gaming tedious. It's more about their ego than about real product reviews.They are always eyeing the next junket.
I travel a lot in business class and find that if my flight was unmemorable, then I'm happy. My last trip on EY in business was lousy for so many reasons (least of all the $15,000 price tag). It was a collision of many events rather than the general product that hacked me off, but was indicative of a casual indifference to passengers (the ME3 get their own market so easily they don't need to fight for it).

NZ is not the best - I recall a former KLM CEO said that if his product was viewed as a VW Golf (good, reliable, dependable, consistent) then he'd be happy not being a Porsche. NZ is a Golf. I use them a lot (100+ times per year) and haven't had a bad flight with them. And it is always a relief to get back onto the NZ network as they do look after Elites when and where they can.
