I prefer a GSD. For me, I find it easier to get a solid GSD than it is to get a solid mal. The majority of mals I have worked have had some type of nerve issue (mostly environmental). The mals I have seen that do have the temperment/drives I like have had a problem with re-directing. I have contemplated getting a mal, but I just don't think they are the right breed for my household. I should also add, that size has nothing to do with it. I actually prefer smaller GSD's. Intimidating? Well, I have yet to find someone willing to cross my 50 pound female, and that includes decoys.
