you get both versions of baldurs gate through gog
but it's pointless anyways, the enhanced edition is better in literally every single way
it's just the first game with the second games engine improvements. they added four completely ignorable characters, while you get more classes, more spells, and a proficiency system that isn't awful. wow so bad.
