Coteaz vs normal Inquisitor

Hey,


Tactical question from a GK noob here (i still haven't fielded my new Draigowing yet...althought everything is on bases now). Simple question, most likely more complicated answer:

When do you choose Coteaz and when do you default to a regular Inquisitor?

Coteaz is and should be your default inquisitor, because of the stuff he brings to your game. Seizing the Initiative, 2 Psychic powers from Divination is excellent. But the best part of him is, you can field henchmen squads as troops, a.k.a. really cheap troops, leaving you open to use other more expensive choices, and still have a very solid force.
 
A regular Inquisitor on the other hand is not an automatic choice. Every ordo has its own goodies to equip your inquisitor with, but appart from that is nothing to write home about. Perhaps the fact that he can also be a Psyker, a very cheap one, is also a good thing to remember.
 
With the new Inquisition Codex, the regular Inquisitor has become more useful. You can have up to 4 Inquisitors with Prescience in a GK army allied with Inquisition,  which is really nice to say the least.

The thing is though, in my case, that i wont make use of henchmen in my draigowing list and that i might need the servo skulls of a regular inquisitor. But i dont know if having the skulls is better than the rest of coteaz advantages...

You still get the steal I, and for the points it is hard to go past with D6 S4 shooting attacks and 2nd level Psy. The next best inquisitor is terminator armour with Psy cannon and 1st level (about 10 points more). If makeing use of skulls this is the one I would be going for (would be more with skulls)
