I have a way of ranking villains specific to my tastes. We have a multitude of categories.
1.- Reasoning
2.- Mental state
3.- Level of violence
4.- Threat Level
5.- Types of Atrocities They are willing to commit
1. Both have no real reason to be attacking ponykind, but chrysalis at least comes off at first as wanting to provide food for her subjects, I'd give a pass to her had she not seen how well off her hive was after reformation, then ditched it because they didn't do things her way. I take reasoning seriously because I personally dont care much for villains who are evil because they are evil. Villains in real life never see what they're doing as wrong in fact quite the opposite, they find themselves to be the morally just ones. Building character depth and backstory is just as important and unfortunately neither Tirek nor Chrysalis have good reasons to be doing this, so neither get a point in reasoning
2. The mental state of villains can be considered in multiple ways, the more unhinged a villain is the more dangerous they can be, yet the more mentally sound a villain the more calculated their schemes can be. Chrysalis seems to be relatively competent at the earliest portion of the series, in fact Twilight was her only foil had she not been there during the wedding, she would've won, and that's even seen in the future where she took over. Tirek never had much for direction though, he made a move the moment he got out of Tartarus, had discord not been there to help him, Tirek would've been an easy capture, therefore a point goes to **chrysalis**.
3. Level of violence is how violent a character is, how much damage they can do. Queen Chrysalis and Tirek are both tied by outside assistance, chrysalis needs love to increase her power, and Tirek needs to absorb pony magic. As for the most violent it would have to go to Tirek, he's shown to be a powerhouse, requiring Twilight to have the powers of all 3 other princesses just to become his equal, and they have a battle that clearly shows Twilight herself would've been powerless in this situation, were she to have fought him on her own using only her power. **Tirek** gets the point here
4. This goes to Tirek with no contest as we see in a future where he won, that he goes on to destroy everything and presumably kill every pony in his path, unrestrained with his magic beams, theirfore a point goes to **Tirek** here
5. As for Types of Atrocities, this point goes to Tirek again. Tirek has used partners for his own benefit, he destroyed everything in one universe and even potentially eradicated the entire pony population, whereas in chrysalis's future everything is still intact, the world is taken over and her changelings remain at her side, and even offering to spare the other pony if Zecora cooperates instead of rebelling against her. Making **Tirek** the most willing to commit the most violent atrocities so he gets the point.
Chrysalis = 1
Tirek = 3
Tirek wins this match.
