I especially like the convenience of pressure canned meats. They work fine for most casseroles, soups and stews... and canned ground beef can be turned into tacos or chili or added to spaghetti sauce in 3 shakes of a lamb's tail. You don't have to worry about your freezer dying and losing all your food, you don't have to worry about freezer burn, and you don't have to remember to thaw it out the night before.
And canning meat is so incredibly easy! I do prefer browning the meat first rather than using raw pack, because I feel it tastes just a little better and there's less shrinkage during the canning process
On the subject of canning pumpkin and squash... This past winter I tried dehydrating some instead. I haven't used it yet so I don't know how successful that will be.
