Yeah, I would probably go with Bradyman to an extent.
You don't specify how old you think Exador is, but he is considered a true prodigy, and both sides of this issue are brought up by other observers in future discussions.
A) Without him, even more incompetent people would not have gotten so far. I'm talking about you--Storm Lords!
B) His track record vs Tom and Lenamare is pretty bad.
That being said, he did wipe out an entire adjoining nation in a fit of pique and terrorized Turelane for several generations.
To be fair, the truly scary one is Lenamare. Either that or Lenamare demonstrate's Exador's incompetence, depending on your perspective.
It is not inconceivable that someone who is truly evil and yet, supremely incompetent, might accidentally (with help???) raise to the highest heights of power and privilege (you know "Most powerful man on Planet X" etc). I mean, obviously, this would never happen on your Earth, but it does sometimes happen on some worlds.
Few things, both Exador and Ramses are very young, and up and coming, "fast track" archdemons, neither is over 5,000 years old.
Ramses is, of course, Ramses the Great/Damned/The Mummy etc. Bess and friends talk about how he got his (mortal/Pharaoh) ass handed to him by the Demiurge between a set of nasty plagues and losing most of his army in the Red Sea when Moses and friends fled Egypt. Talk about embarrassing!
Exador is about the same age, both are very young, and were very active within a few thousand years of becoming demons. This is, actually, quite impressive. So they are very good, but very young, as archdemons go. So we can forgive some stupidity.
But, Lenamare is a mortal, and yet somehow who manages to compete on a level playing field with Exador. Very embarrassing. Makes you wonder if Lenamare is secretly a demon prince.
He isn't, just thought I'd freak you!
Trevin? More like Dame Edna crossed with Karen Carpenter at 90 than Dame Helen Mirren at any age. Or maybe Sylvia Fine (Fran Fine's (the Nanny)'s mother) dressed like Barbara Eden in I Dream of Jeanie?
As far as Elrose, Conjurors have very little respect for Thaumaturge's, Sorcerer's or Enchanters. Basically, they only appreciate other Conjurors and Pyromancers. People that cause big, deadly explosions, or people who can summon others to create massive blood baths.
Phoenix Cycle will be heavily detailed in the future....
