They are smoother textured than turkey feathers too. he seem to hold up as well in my limited experience. And, as said above, they are waterproof. I process all my feathers by splitting the quill, trimming off excess quill etc. I then put the feather in my fletching clamp and use a block sander to reduce the quill to final thickness.
Sometimes I strip the feathers instead. Much faster, but not as easy to glue on. When glued, however, the actual vane of the feather is right down on the shaft with not rough edges.
