Top 5 Sith/Darksider/lightsaber wielding villain

Mine are

5: Baylan Skoll

4: Vader

3: Palpatine

2: Qimir

2: General Grievous

Power wise? Qimir, grievous and arguably even Baylan do not even make the top5.

1. Vader

2. Sidious

3. Dooku

4. Maul

5. Baylan/Ventress

Probably plagueis could make the list, but he doesn’t have many feats

If you mean in terms of preference:

1. Maul

2. Vader

3. Dooku

4. Grievous

5. Ventress

Power

1. Sidious
2. vader
3. Dooku
4. Exim Panshard
