No, but it's useful against Cheren and Bianca, Cynthia (excellent counter to Garchomp), and the Elite 4. However, arguably the best Pokemon for post-game would be Volcarona (train up a Larvesta to 50-something, or just catch the one in Relic Castle), as long as it has a set with Bug Buzz and Quiver Dance. Evolving a Riolu from Challenger's Cave into Lucario is a good idea too.

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.
well, it depends. If you train it well, that pokemon wuill bethe best in your pokemon world.BUT I highly suggest you train black kyurem because its stronger than white kyurem.
Definitely Marriland.
