Sith value power above all else, these things that you mention dont make a great Sith. They would consider Revan the greatest of them, he is a master of war, corruption, manipultaion and death. Malakor V, a Sith greatest achievement realised. He killed men, beasts, enemies, allies and a planet that day... all through his choices.
I suggest we end this and agree to disagree after this in order to avoid derailing the thread/causing a flame war, but you just listed everything I listed about Sidious.
"Sith value power above all else"
No Sith had as much power as Sidious. He ruled the galaxy. An entire GALAXY. You can't get much more power than that.
"Master of war"
Sidious was fighting a two front war... against himself. He was in control of both the Republic's army, later the Empire's army, and the Seperatists through Count Dooku. Also, up until Galen Marek and Luke Skywalker, he kept all rebellion in check as emperor.
"Corruption, manipulation"
This is exactly how Sidious, as Palpatine, gained power. He manipulate and corrupted hundreds of politicians, generals, and the like in order to take over.
"Death"
If you mean killing thousands, Sidious does cover this. I'll admit I don't know who killed more, so Revan may have the upper hand here, but if we're talking power over death, Sidious wins. He was the first Sith to come back from the grave. He created clones of himself, and brought his spirit back from death using the force to inhabit the clones. Revan never did this, as it can only be assumed he died a Jedi.
As for killing beasts, men, and destroying a planet, well... Death Star. 'Nuff said.
I'm sorry if I'm getting all Sidious-fanboy on ya, but you have to look at the facts.

Again, let's end this here. I'm willing to continue the discussion through PM's if we keep it civil, which I'm sure we can manage, but we shouldn't derail this thread any further
