I perfer lard, or drippings, or even veg. oil.
The canned butter is very expensive. But it is very, very good, too. Better than American butter. I bought a sample, and used it.
The cheese is also good, but I like mine better.
If push comes to shove that butter and cheese aren't available. I'll make my own. I have those skillsets and the skillsets to build the equipment, if mine is gone.
The critters required are nearby.

If I had a husband and children, I would freak out making sure there was plenty for the different appetites.
I know. Too many people are survivalists, too few homesteaders.
I love lard, almost as much as butter. Course lard will store for a good amount of time, and as you said you can make your own if need be.
Also found a hand operated oil press and grow various oilseeds. Worse comes to worse I can grow my oil.
