Now as for what I was alluding to here, I'm going to copy down a little list here that helped decide the outcome of
Cinner vs Ako.
AP: Cobalt (via digging into her power she can fight a 6-C like Boss Mode Marx)
LS: About equal (Asuna does have a 'likely Class T' ranking but this is unclear)
Speed: Cobalt (Asuna at first, but Cobalt can close and surpass it)
Durability: About equal, both have a barrier the other can't bypass as well
IQ: Cobalt (Extraordinary genius is far beyond regular Genius, Cobalt surpasses another extraordinary genius in Marx Gemini in general and in battle IQ))
Battle IQ: Cobalt (her BIQ surpasses Marx's)
Skill: About equal (proven throughout this argument)
Experience: About equal (Both inexperienced with their powers)
Offense: Cobalt
Senses: Asuna (Danger Sense surpasses Cobalt's extrasensory)
Planning: Cobalt (Cobalt will be coming up with multiple highly complex strategies quickly over the duration of the battle)
Defense: Asuna
Pure Hax: Asuna (mainly on the defensive end)
Agility: About equal (Both shown dodging extreme danmaku)
Regen: About equal (healing magic/reverse dissipation help)
Range: About equal (Discounting hyperspace gates and riftways)
Stamina: Asuna (Although Cobalt's isn't something to underestimate)
Endurance: About equal (Although Asuna can survive normally fatal injuries, Cobalt can't really perish unless her core is destroyed, meaning that she can survive far more fatal damages, although would have an extremely hard time recovering. reverse Dissipation lets Cobalt survive similar injuries)
If I were to divide this all into a points game, where the stat where Asuna or Cobalt lead is equal to one point (stats they are considered equal in is worth a point for both), we can get a clearer picture.
The score here would add up to this
Cobalt: 14
Asuna: 12
According to this, Cobalt has the overall advantage in the fight exactly as I've been arguing.
