Well let's break it down:

Personality: Revan is capable of switching personalities. This is a good thing because it makes him unreadable in combat. It is a bad thing because it also means that he has a harder time committing to a single plan when they keep going for different plans or as the saying goes "A bad captain manning the ship is far better than having three good captains manning the ship" or "Too many chefs in the kitchen spoil the stew" (I am also assuming he is capable of switching personalities based on the combat situation, something that no one can truly control) Carissa is quite essentric, and knowledgable which can be a major boon in combat as she is the one who obtains all the information needed for a mission.

Aura/Semblance: Revan's ability to counter is more practical in a fight than Carissa's reconaissance abilities

Weapons, Skills, and Abilities: Carissa is well rounded in what she is capable of due to multiple weapon forms, and enhanced skills while Revan seems to be the most dangerous at close and medium range

I would say that Carissa would win due to the ability to gather info, and the ability to stick to a general plan of attack.
