I can't help you with the saws you are comparing it to, but I can tell you that it way out cuts the 385xp. My only complaint is that it is a little heavy, but or milling that should not be a concern. I generally only use mine for cutting stumps and occasionally bucking up large trees. I just purchased an 066 project saw, but have not put it back together. I am waiting on Bailey's to get the big bore kits in.
