That's not saying much.
The 30k SW units are the poorest legion units in the 30k range, mainly because there was little interest in the FW studio in the legion and little effort was put in.
The 40k stuff is either very old, or comes from the wolfy mcwolf era when space wolves became a caricature.
Going back to the bloodclaw/grey hunter/longfang/wolfguard paradigm was obviously a sensible thing to do.
