So lets take a look at their stats and compare them:
AP/Striking Strength: At least 134 kt (Teresa) vs at least 516 kt (Raven) so right off the bat Raven has an almost 4x AP advantage.
Durability: Unknown (Teresa, though im guessing this should be High 7-C scaling to her AP?) vs at least 516 kt, 2.064 mt with aura
Speed: Equalized (As Quicksword has a solid number as opposed to being just a normal amp it would be equalized as well here as per SBA)
Lifting Strength: At least Class 25 (Teresa) vs At least Class K (Raven) (This would actually come into play here since swordswomen, allowing Raven to overpower her physically in blade clashes)
Stamina: Teresa's stamina description is odd seeing as it lacks an actual timeframe for how long she can actually remain in active combat for, whereas Raven has an actual timeframe. They'll be considered even until this is clarified.
Range: At least Tens of Meters (Teresa) vs Hundreds of Meters to Several Kilometers (Raven)
Intelligence/Skill: Teresa's feats have already been explained above so i'll list some of Raven's:
- Raven as a child, with no formal training, was able to get into Beacon through sheer skill, which normally requires several years of training at a combat school to do.
- Trained directly under Ozpin for the majority of her Beacon career and became skilled enough that he entrusted her with magic as well as becoming a part of his inner circle.
- After she left Beacon she continued training virtually non-stop as a means of protecting her tribe and eventually came into her Maiden powers, training further with this power and becoming so skilled and precise with it that despite standing directly in front of him she was able to fool Mercury Black, whose ability to analyze opponents and their abilities is so great that he was able to determine Pyrrha's semblance (which she managed to keep hidden from the world for her entire life) after just a few seconds of combat, to the point that he had no idea that she was using the powers of a Maiden.
- Outmatched Cinder in single combat, who in turn defeated Ozpin.
- Neo, who had just casually skill stomped Yang in a 1v1 fight and who has no knowledge of Raven being a maiden, was terrified of even trying to fight her.
- Her fighting style revolves around using a variety of sword techniques coupled with her constantly changing Dust blades and elemental powers as a means of keeping the opponent constantly off balance and unable to properly adapt to her fighting style.
- Described on multiple occasions to be equal in skill to Qrow, who in turn 1. embarrassed Winter Schnee in 1v1 combat and outmatched her in skill while he was drunk, 2. matched Clover, leader of a team of Atlas' most elite and skilled huntsmen, 3. made Mercury Black, a world class assassin who was trained to be able to outmatch other fighters through sheer combat skill to compensate for his lack of a semblance along with the analytical skill i listed above, flee on sight, and 4. was described by Ozpin as being the single greatest wielders of his scythe, which Ozpin personally described as one of the most dangerous weapons ever known to man.
Abilities/Versatility: Both have Superhuman Physical Characteristics, Weapon Mastery, Stat Amps, ESP, and Flight
- Raven: Forcefield Creation (Passive Aura forcefield, Passive bubble shield, active personal barriers), Enhanced Senses (Can use her Aura to sharpen her senses), Regeneration (Mid-Low), Dust Manipulation (Her sword uses blades made of Dust which grants her Air Manipulation, Ice Manipulation, Fire Manipulation, Water Manipulation, Electricity Manipulation, and Gravity Manipulation), Magic, Fire Manipulation, Weather Manipulation, Ice Manipulation, Air Manipulation, Electricity Manipulation, Earth Manipulation, Weapon Creation, and Telekinesis
- Teresa: Yoki detection that acts as pseudo-precognition, Social Influencing (Can encourage awakened beings to regain their senses), Technique Mimicry (Can easily imitate other warriors' techniques), Afterimage Creation, Regeneration (Low-Mid), Shapeshifting, Elasticity and Body Control (She can stretch her arms to great lengths similar to Helen)
- As Raven doesnt have Yoki and, after reading what Yoki is in Claymore, Aura would not be equalized to Yoki, Teresa's Yoki precog wouldnt work here, and neither would her Social Influencing. Raven also has very few actual techniques that can be copied by Teresa as the majority of her powerset comes from her use of Dust and Magic, so technique mimicry is borderline useless here as well.
So taking speed equalization into account:
Raven:
- Higher AP
- Higher Durability both physically and with aura and barriers
- Higher Lifting Strength
- Higher Striking Strength
- Higher Range
- Greater Versatility
- -The longer Raven fights the lower her Aura levels will drop from taking damage and if broken will leave her vulnerable to lasting damage
Teresa:
- Skill (?)
- Regen
- -Quicksword can only be used once in combat
- -Regen can be bypassed via decapitation/freezing
Equal:
So uh...yeah Raven holds almost every advantage here barring the clarifications on the stamina and durability and the debate about skill
