One of the only differences of the games is that they both have an exclusive area. Pokemon Black has Black City, which is full of trainers to battle. Pokemon White has White Forest, which has both trainers and wild Pokemon that are exclusive to White. In other words, White version has more kinds of Pokemon, so I'd say it's your best choice.
