I do both sizes as well, but DON'T stuff them.
You will have liquid spill out during the process and your jars will not seal.
I do pints for sharing or single meals and sandwiches.
Quarts are for adding to stews/meat pies and larger meals.
If you are concerned about feeding a family of 4 I would suggest going primarily with quarts. You will always have enough for the family and it is much less work. It is a lot easier and quicker to fill 8 quarts vs 16 pints.
