I have both of those mages as Thralls and they are among the best of those types you can normally thrall.
If you can thrall anyone with your mod though , I suppose J `zargo would be the best since he is the only character that naturally scales up to level 81.
Second choice would be a Volkihar Master Vampire who caps at level 53 but has insanely buffed stats .
Both will throw Chain Lightning from a distance if they have enough magicka.
Illia is a superior ice mage who casts Ice Spears with deadly effect. (cap lvl 40)
Illia also will cast Ice Storm but because of it`s magicka cost , I recommend giving her a Staff of Ice Storms for repeated attacks.
Almost all Thralls (including non-mages) will throw fire from range if you give them one or two Staffs of Fireballs to use (and no bow).
Dual-wielding : Forsworn Ravagers or Briarhearts. Make sure the off-hand weapon is a forsworn sword or axe to insure maximum usage.
Long Range Archer : Northwatch Archer or Aela.
No thrall will use the Dead Thrall spell themselves. Some will use Raise Zombie or Revenant (vampires,etc.) but if you want extra players on the field , then give thralls a Summoning staff of Familiars , Atronach, etc.
Thralls absolutely will use Sanguine Rose to conjure a dremora almost every battle.
