Cow hide I find to be too thin and tough once it gets wet and deer skin not durable enough. I've never tried pigskin in anything but footballs.

I switch between gostskin and auto mechanics gloves. I use them for gardening, yard work, tree planting, grabage clen-up and bush work. I have pairs in bobs, vehicle kits and the garage. I find them both great. They're both comfortable and durable.
