Personally i would not use Brazzers as the yardstick against to measure NA.
Brazzers IMO is even more riddled with "big fake tit dinosaurs" than NA, and quite a lot rather more at a loss at how to make the most of the upcuming generation of young "natural tits" female beauties like Anya Olsen, Sydney Cole, Kimmy Granger, Jill Kassidy, Nina North etc. than what I find NA to be.
That the camera work and lighting in the scenes over at Brazzers is better than at NA, for me is more or less irrelevant, compared to the aforementioned "big fake tit dinosaurs"-factor.
To me Brazzers is more or less the same as NA, if not rather too much of the same, except for creampie where they are rather less generous.
And of the "old mainstream sites" NA, Brazzers, Bangbros, RK, DP etc., NA is the one that most regularly feature creampie from my experience. And that decides the matter for me. Thus NA is the only one of those "old" sites with wich I still have a membership. Though when Brazzers have generated enough new suitably interesting creampie scenes, I might rejoin for a short while to download those scenes before i quit again. Most of the anal shit etc. that Brazzers is riddled with, I can do without.
That said, even though the 3 Meyer Lansky sites (Blacked, Vixen ...) have got a lot of accolades over the last few years, I even find the format on those sites rather repetitive after a while. Though his best scenes, like the legendary 6-some bbb/ggg creampie group scene with Elsa Jean, Sydney Cole & Rachel James, The anal scene with Alaina Dawson or creampie scenes with Natalia Starr and Ally Tate etc. in many ways are in a league of their own.
