IMHO - Some beers taste about the same whether from bottles or draught, others do not.
For me, a Thai lager is a Thai lager so I would just go for the cheapest version (volume for volume).
But (for example) there is a huge difference between a pint of draught Guinness and the bottled version. I would choose the pint, even at twice the price.
So I voted "Either, depending on ......"
