There is no such thing as a "best pokemon". It depends on your standards, views and preferences. If you're referring to weaknesses, it would be Kingdra, as it has only one weakness, or Sableye if you will import it from R/S, because it has no weaknesses. Otherwise, it is all personal preference. No Pokemon will be able to beat everything in the game, which is why you need a good party instead of just one Pokemon.
