Top 4 separatist leaders

They must be non sensitive. I would put top three, but I swear someone will put general greivous.

non Force sensitive i take it

yes Grievous IS a separatist leader hes commander of the army so i dunno why you'd point him out

1. General Grievous - Commandr of the Droid Army
2. Poggle - chief weapons/ droid manufacturer
3. Nute Gunray - head of the Trade Federation; the biggest contingent in the CIS
4. San Hill - the money behind the CIS

Are basing this on millitary leaders? Or like, even the politicians?

I’m talking like strategist, you know character ps like trench

Well, excluding Dooku and Sev'rance Tann, and focusing only on military tactics and leadership:
1. Grievous
2. Trench
3. Durge
4. Wat Tambor

What was trench best at according to strategies?

General tambor is probably smarter than the bounty hunter
