Let's see shall we

Leader

In terms of weapons, it's an easy edge for Imperius. A spear is already a much more potent and deadly weapon than a staff, even with the great power held within it but what Solarion is far more than a normal spear and is powerful enough destroy even the most powerful of demons in a single strike. Magicwise it would appear that Saruman focuses more on offensive based magic such as lightning and fireballs whereas Imperius is more defensive minded with his teleportation and flight. Overall I have to give the edge to Imperius simply because his teleportation and flight will make it very hard for Saruman to use his offensive spells and in close quarters Solarion is a far superior weapon to a simple staff. Saruman could always try to use his telekinesis to remove Solarion from the equation but since Imperius can summon it at will (and has telekinesis of his own in any case) I can't see it being all the effective.

Edge: The Angiris Council 

Second in Command 

I'm going to give this one straight to Gandalf. Tyrael lacks the versatility of Imperius when it comes to magic and more importantly his sword, El'druin, cannot harm beings of righteous intent which is pretty much the embodiment of Gandalf's whole character. Gandalf is rocking a wide variety of magical abilities as well as being a skilled staff and sword fighter and should have little trouble dealing with the Archangel of Justice.

Edge: The Istari
