User blog comment:Appelmonkey/Rematch: Sayaka Miki (Puella Magi Madoka Magica) vs. Kirito (Sword Art Online)/@comment-422690-20151223232125

So...

Melee: Sayaka gets this handily with her cutlasses. Excalibur's flashy, but Kirito can't throw it and, more importantly, he only has the one. Sayaka can throw her cutlasses with impressive accuracy (Becuz magickz), and she has a literally infinite number of them. Not to mention this is Sayaka from Rebellion, where she has actual skill to back her up rather than just relying on her healing to keep her going. Overall, Sayaka's got a major edge in weaponry.

Powers: Sayaka wins again. While the pair have very similar powersets, Sayaka's got everything better. Kirito can keep going past major wounds, but Sayaka is a Madoka Magica-verse Magical Girl. As Akemi Homura showed in Rebellion, this means she can get shot point-blank in the face with a high-caliber handgun and be perfectly fine seconds later. Less, since she has a better passive healing ability than Homura does. On top of that, her healing magic is also an active power - she can effortlessly heal multiple deep lacerations and likely several broken bones. The only thing Kirito has on her is flight, and she can mimic that, as seen in her fight against Elsa Maria. Even without any psuedo-flight, she can throw those cutlasses of hers with a very high level of accuracy. Sayaka simply outclasses Kirito here.

Giant Form: Sayaka wins this again, for the simple reason that Oktavia is a summon rather than a transformation in Rebellion. When Kirito uses Metamorphosis, he loses his own ability to fightin exchange for becoming that Minotaur thing in the pic. Oktavia is summoned by Sayaka, and functions as an extension of her will. This means hse has complete control over Oktavia while being able to fight herself, essentially turning this into a two-on-one match. Not to mention the actual summon sequence for Oktavia is quite unorthodox and will likely shock or horrify Kirito, especially with his aversion to killing. Few people can watch a teenage girl stab her own heart out through her chest and remain unfazed.

X-Factors: Based on what I'm seeing here, Sayaka has more experience, is more willing to kill, and has better mental health (again, it's important to note that this is Sayaka from Rebellion, not the first season). She's better equipped to be a fighter in the intangibles, too.

Overall: Overall, I think Sayaka can win this one. She has the overwhelming edge in weapons and in X-Factors. Furthermore, she has one major edge - determination. She will not quit fighting until she dies; combine this with her Soul Gem being her only weak point and you've got someone who will give a beating, take a beating, and come out on top, not matter how battered and bloody she gets. It won't be as much of a stomp as the edges hint at; Kirito is the Marty Stu protagonist of a Shounen series, after all. He'll put up a good fight. But Sayaka will ultimately crush him.
