I prefer cans - they are lighter and so easier to carry since I put them in my back pack, they take up less space, they cool faster in the fridge (less thermal mass), don't break and I crush them when I'm done so they use way less trash space.

Probably gonna get filleted, flogged, flailed and handed my head on a platter by guys like tradewinds as usual for having a contrary opinion ... heavy sigh - hit me!
