Rank 2: Darth Sidious
Darth Sidious, the probably most powerful Sith Lord of all time, is not a big fan of lightsabers, as he sees them as outdated and part of the Jedi tradition, but this does not stop him from using them for a long time and being a true master in combat.
Instead of focusing on a single technique, he blends all seven forms into an individual, personal style. This allows him to respond to all attacks and strike unmercifully. Sidious is a very fast fighter who has no problem even against multiple opponents at the same time.
This becomes evident in Episode 3, when he duels three Jedi Masters simultaneously during his attempted arrest by Mace Windu and kills all three – including the very talented Kit Fisto. Only Windu manages to defeat Sidious. Later, the Sith forces Yoda to kneel, which results in the old Jedi Master going into exile.
