I have both !
A upright for household items & a 9 cu ft.chest
In garage for wild game & bulky items.
I put butts , briskest , whole poultry etc. in chest,
Nothing to small.
We'll packaged items will keep 2-3 times as long in chest as upright for the reasons mentioned.
I have the same setup. We had a chest for years and it can be a pain for smaller things like corn dogs, bacon, egg rolls. We bought an upright not too long ago and it holds all the smaller things and things you need to get to frequently and the frozen veggies we are stocking up on now. . The chest holds all the meat, butts and stuff I pick up on sale and vac bag to cook later. We have the upright, the chest, the freezer in the fridge in the kitchen and the freezer in the beer fridge in the basement.
