You can’t go wrong with either one but the F1 is quite a bit lighter. If weight isn’t an issue you might also consider a Mako if you are determined to get an Eskimo. It’s a solid auger and many places have them on sale right now. Some stores have the Mako cheaper than the Stingray which I find a bit odd. I get a bigger, faster, more powerful auger for less money? Okay...done deal.
