Which hero is the best in the Tribes of the East expansion?

The warlock can have an attack stat that exceeds his magic power, so if the game drags on and you realize that you won't get far with just Chaos magic, you have to pay attention to the attack stat as well, and no one is saying to ignore magic altogether. It doesn't matter what you call the hero (warrior, warrior-mage, or something else); it's clear that one school of magic will be developed anyway. When I say warrior-TE, I mean that instead of magical skills (sorcery, a second school of magic), combat skills will be taken (leadership, defense, whatever you get).

The fact that she has Chaos magic is good; there's a place to put the magic power, and then you choose skills to your liking for the warrior.

The longer the game lasts, the less useful Chaos magic becomes, although it is relevant for the dark knight at any stage of the game, except perhaps in the very late game. But if you're building a warrior-TE, summoning will look better. If you could choose skills to your liking... then everyone would have perfect builds; but as it is, you have to choose from what is given, and the TE gives warrior skills rather reluctantly (except for attack), while Kifira has leadership from the start. Of course, Battle Blessings is a very useful skill, especially at the start, but unlike leadership, it is easily obtained. There is no doubt that the warlock will develop his attack stat if he wants to, but what about leadership? And in order for Sorgall's ability to work, you first have to reach the target, survive the counterattack and subsequent attacks from units, and attack those who are standing next to the riders. However, the opponent does not arrange his formation to make it so convenient, and the primary targets may be on the opposite end of the field from the riders.
