From the consumers point of view, cans are the easiest to store and handle. They even have a can crushing device which works easily with one downward push.
Glass is a lot heavier and more prone to accidental breakage.
Plastic bottles (particularly the large 2 or 3 liter bottles are a huge PITA to deal with. You need large trash bags to put them in etc. Ive discovered this the hard way upon moving to Michigan. Ten cents is added to the purchase of every bottle and can so unless one is rich, you save them to bring back to store to get your money back.
But those large plastic bottles are awkward space hogs. I hate it.
And if you want to get your money back on cans you cant crush them. The machines operate by reading the bar codes. The whole system is a mess. I hate it.
