I like the 20mm for airtight storage of items that do not need to be moved!
I would rather pick-up two 50 cal cans & go..
(balanced load, no back strain)
..than leaning forward & walking like a duck while holding one really heavy 20 mm can which is banging on my knees.
Ask me how I know this !
Also they are really deep...
..makes it hard to grab items not near the surface.
