Agreed. I was actually fairly unimpressed with the Clack skull design (had no interest in buying one, even at the $50 prices they were going for at that time) until I got one on loan and put it on my board. The design is just so clean, and the feeling of pressing on a Clack is perfection. There's something about the design that just works so well, it's kind of weird actually.

yeap, also not a fan of the skull design, but i do still appreciate all of the subtle qualities of the keycap. on the surface, you only see the simple (and flawed) skull, but the color depth/consistency, cap profile/thickness, and the way the design seamlessly blends into the face of the cap are nice touches that the majority of the other artisans lack in their execution (whether by design choice, or by lack of skill/capability). clack's multi-shotting method (especially with the eyes) is also more consistent than any other maker's sculpted, multi-shot cap that i've owned, which makes owning one feel more special.
I actually prefer caps which don't deviate from the general shape of a keycap profile. cc skulls are just a regular keycap shape but with a skull design on the face, nothing on the sides. I think that makes it look great on a board amongst other caps.
^this too. not a lot of places you can "hide" an artisan on a 60% (or less), so low-profile designs where you aren't having to subconsciously brace yourself to press some protruding sculpt are ++. clacks are the best design i've owned in that regard.
of course, their aftermarket prices are ****, and it's difficult for new enthusiasts (aka <1 year in the game) to get a non-bland color due to stagnant supply (which is why k3 is picking up steam again with clones of rarer colorways), so all of those nuances wind up never being realized by most.
