When I want visual quality and all the small movements in the world, it's usually Nagoo who does some fantastic job. His final fantasy pieces in particular were amazing.I agree, ZM is very consistent with his work, i dont remember any delay or similar with the releases, Nagoo personally still is goat, but bulgings did fall off with time, delays and vanishing, personally my favorites now are TheCount and Nagoo
When it comes to creative direction, fetish friendliness and overall story/scenarios, I go for Zmsfm. Quality is there for sure but his main "gimmick" so to say are the variants and customized polls + content variety.
Not to speak of the fact that he consistently spoils people with goodies. This month alone we had 4 animations (Shadowheart one should come so that would be 5) and 4 posters. Some people struggle to make 2 posters in a month.
Aside that, ZM is a really, really, really, really, really nice person.
