Maybe it's some mass illusion, but most people say that drinking from glass bottles tastes significantly better. Personally cans taste bad, plastic somewhat better.
Cans are lined with plastic on the inside, otherwise aluminium would react with acidic soda. There is no practical difference in that regard between a plastic bottle and an aluminium can lined with plastic
I like drinking from a can; your mouth still touches the metal while you drink, so while the flavour of the liquid as such is unaffected, it still changes the overall "flavour experience" (for either better or worse, depending on personal tastes).
If you pour it out in a glass it makes no difference.
