They are all pretty decent.
Azmodan may feel a bit stiff, but has some nice sequences nonetheless. What I dislike the most about him is that he tends to port the same animation over and over for multiple locations. Just look at how many times he ported that reverse cowgirl sequence! For sofa, stairs, sauna, it's everywhere lmao. But his new stuff is always pretty decent. Also he recently created a MF + voyeur sequence for table + seat which is pretty neat.
YrSa is... hm sometimes good, sometimes bad. Pretty much depends. Sometimes his animations may feel too niche (peeing on breasts fetish), or not worked enough, but when it's good, it is good. You just have to dig a bit in. One recent animation I really liked is a reverse cowgirl anal he created for floor. Can't recall the name, but it was really good.
A. Trois is great. He has the same style of Motherlode, but perhaps a bit less precise, less worked. But he does more 3P and rough than Motherlode which is good. What I don't like is the overusing of certain sounds, like a "spooked" one he tends to use a lot of time. Nonetheless one of the best animators around.
If you enjoy my comments, I can share some more opinions, on like minor animators I like
I enjoy reviewing animations.
So many goodies! Thank you so much man!
