I think the rogue titan's (i don't give a damn to "attack titan")hardening is unique because eren can harden the whole body,and by that I mean everything including flesh and bone like when he sealed the gate of shiganshina. Other shifters, so far just able to harden their skin temporary or by default in case of armored titan, and  the wall titan too, since we still can see the flesh and the eye of it when the wall shard falls
