Yes. Or at least very poor.
While their total amount of unique materials isn't even all that bad, they spread their shit over so many different meshes, to make it easier for brainlets to turn off clothes they don't want. The end result is often like 12 skinned mesh renderers and 22 material slots used
A lot of booth models instantly become Medium or even Good if you just merge the meshes in Blender and do absolutely nothing else
Another big one is physbones, booth authors put a new physbone component on every hair strand or every skirt strand instead of using root bones
