Chest freezer sorting: bags or bins?

Chest freezer organization: I’m torn between the cloth grocery bags, or the fancier stacking wire bins. I want to go with bags because it’s cheaper, but trying a few so far I see they don’t make the most of vertical space.

I have a 7 cubic feet freezer. Mostly meats, cheeses, and veggies so far. Has anyone tried both and has thoughts?
