Too loud, too easily defeated by an opponent with a firearm. In an emergency, I suppose it would work fine, but I'd still rather have a good shotgun for up close work. Maybe the chain saw afterwards.....
Is this even a real question? I think I'd rather have a large stick than a chainsaw. Have you ever even picked up a chainsaw? Notice how heavy it is? Think you could swing that thing around and hack people with it for any length of time?
You might be better off just chucking it at the attacker and then running.
Perhaps, if I am very lucky, the feeble efforts of my lifetime will someday be noticed, and maybe, in some small way, they will be acknowledged as the greatest works of genius ever created by Man.

When the Ship Hits The Sand, use whatever it takes to survive. Are there more desireable options? Yes, but you use what you have. I can envision being in the mountains taking down a tree, and suddenly attacked by either 2, or 4 legged critters.
