Gargoyles are also non-undead, which prevents them from being toasted by Flambeaus and similar that might be a threat to certain other common SC chasses. Consider giving it Armor of Souls or something like that.
They also have better attack than Crushers, and have flight as an advantage over Living Statues.

I've used GoR'd gargoyles in SP, they seemed pretty good. Nice base prot, and the never healing wasn't that big of a hinderance with lifedrain weapon. IIRC they have a somewhat low attack/def (10 each), though. I believe they have full slots as well.
