I said it in the other thread, but these are so good it bears repeating: the Inhumans sets are insanely good!!
Triton - He (appears to have) the dedicated sculpting he was always going to need to be done right. The costume details all look on point, even including the piping along his torso and limbs, he appears to have butterflies, plus classic and modern heads. And hey! Swim hands!
Black Bolt - The least exciting but he still looks solid - a full complement of heads and hands, extra wing pieces, and Vulcan is a good body for him. Sculpted costume details would have put him over the top, but I'm not fussed about it.
Medusa - I really wasn't expecting much from her in this set, but the new figure looks pretty amazing. Classic costume, two faceplates (a first for ML at this scale I believe), a properly articulated body, and hair articulation.
Gorgon - I'm with Beamish in saying this guy might end up being an all-time favorite. He's based on the Caliban body (his torso and arms at least) so he's gonna be a big boy. The costume details and everything else about him is absolutely amazing.
Between these sets and Crystal/Lockjaw the Inhumans have gotten an insane amount of love in ML in the last year. I love to see it!
