I have one of these.

I think the one I have is the 15 quart one based on the capacity given.
It does 6 quarts comfortably or about 12 - 14 pints, which can be stacked.
It’s as big as I can reasonably handle. I doubt I could manage the 21 quart size. Those suckers are heavy.
Thank you! That pressure canner in the running, for sure! I think Ellendra got one recently? Can’t remember...
