If you just want to get hammered....it does not matter. Drink any old swill from the bottle or can.
Quality crafted Ales and Lagers reach full flavor potential when poured into a glass...and served at a temperature that suits their type of fermentation either warm top fermentation (ales, stouts) or cool bottom type (lager, bock).
The act of pouring discharges some of the carbonation from the bottle, giving beer I believe a smoother more well-rounded taste.
Most kegged beer I find repulsive, simply because the dispensing equipment is (usually) not properly maintained.
Hey, if you paid for it, drink it any way you like.
