Alpha Patroklos: Being i8 gives this CE a lot of potential use. It can punish a lot of moves, it's application can be used in a lot of versatile ways. Ability to combo off 2A is just icing on the cake.
Hilde: The fact that you can use it as a step punisher, from distance, and it's damage makes this CE incredibly useful. As Hussler mentioned before, "Limited use of Meter = more CE's." And judging from her Brave Edge's, she doesn't seem to have much need for them.
Algol: Has the most disgusting damage- and can be used for potential RO (The combo follow up). It's application is pretty versatile as well.
Patroklos: RO, and application towards combos is it's main purpose. I'd also like to add that his Meter gain is probably the best in the game. Having the ability to build meter, and have this CE in your arsenal is disgusting.
Astaroth: With activation frames at i18, this can be used as a punish. Leads to large damage, and potential RO/Wallsplat. Also, it's a unbreakable grab with incredible range.
