What's the difference in training Maul would have gotten as an assassin instead of a true Sith Lord? Did Vader get any Sith training? (Star Wars)

Most Sith are given just the basics of Force training, and then encourages to discover their own path. This is how Maul was trained, and it was how Vader trained his apprentice Galen Marek.

Vader himself (and Tyrannus) never got any additional training, since they were quite adept at the Force when they became Sith.
