Another that immediately comes to mind is Akatsuki Giken, you could say he's the Japanese equivalent. Draws mostly the same thing which he barely knows how to draw anyway, but goddamn it hits the spot every time. His eromangas are popular on Sad Panda.

I shouldn't be posting loli since this isn't the board for that but I feel an honorable mention would be Anyannko. He's changed a lot and does work for Comic LO now, and his starting point isn't as immediately in-your-face bad as the others mentioned, but in comparison to what he makes now it was definitely a rocky start. Very wonky proportions in an attempt to be more realistic, and the flat anime faces look a little funny on those bodies.

Still, very cute I think and I really enjoy both eras.

for me its circle anco. Its fappable but it looks really 'stiff' and the pen0r and manko look weird. So i try to avoid posting it.
