No need to discuss this. Bottles > Cans.
I don't care, and will usually poor it into a glass regarldess. I do think of the two cans are easier to drink out of.
All modern day cans (beer or soda) and coated inside with a very thin layer of plastic to keeo the beer from absorbing any "can taste." The cans themselves are made from a type of alumnium that is not supposed to leatch any taste. The only time beer in a can comes incontact with metal is when it flows through the opening. I think if you taste "can" it's all in your head. Also beer in cans isn't effected at all by the light which alters the taste profile of many bottled beers if they are not stored properly.
