The most powerful warrior.

Inquisitors are no worse than liches!

Yeah, sure. An Archlich deals 18.4-23 damage to an Inquisitor. An Inquisitor deals 7.8-10.4 damage to an Archlich. 80 HP doesn't compensate for such meager damage, because even in melee combat, it's clearly too low for level 5. He's not much better as a caster either. And he doesn't have the Deadly Cloud spell, and his initiative (which is twice as important for archers) is lower. Inquisitors are really only good for converting them into Paladins. Haven has many of its own advantages, but Inquisitors, in my opinion, are not among them.
