Oh, ok. That makes this more interesting. They should be pretty equal from what I see.
Let's see. The Silver Eyes will be no issue here, I guess.
In Mid-Range I think Kats Stasis Field throwing and Gravity Typhoon techniques have an advantage over Ruby's shooting. She can launch multiple projectiles at once or in quick succession this way.
Due to the large recoil of Crescent Rose, I imagine that doing such rapid fire shooting is more difficult for Ruby. At least when she has to dodge at the same time.
This is enhanced due to the fact that I don't think Ruby has the leisure to employ the rifle mode for mid-range shooting or to embed the blade into the ground. That is due to the fact that Kat can teleport with wormholes, meaning that she could at any point appear right behind Ruby. If she doesn't have her melee weapon ready to defend and counter-attack then, she will take hits. Due to her Aura she initially has to option to tank those, but that wouldn't give her an advantage, as Kat can just go back to mid range at any time.
In long range, like at a hundred meters +, I could see Ruby having an advantage as Kat doesn't often fight at that range, but I can't see how Ruby would maintain that distance with Kat's teleportation. In fact, hitting Kat over that range would be very hard.
Now, in close combat I think Ruby's scythe mastery is greater than Kat's hand to hand combat capabilities. If it's a fight of Gravity Kicks & Spiral Claws against Ruby's Scythe and gun combination Ruby would get out on top.
However, the Lunar Style in particular can make it difficult for Ruby. Quick chains of teleportation which are immediately followed by kicks is hard to keep up with and the Vortex Field can stun her and reflect her attacks.
The most lethal attack Kat has in close combat would be her Black Hole attacks of course. I don't think it is healthy for Ruby to get caught in these, so she must at any time be ready to disengage, which prevents her from fully investing into close combat. Without knowledge the black hole can also take her offguard.
Ruby's semblance can of course be used to further incerase her close combat ability. With teleports and the increased speed offered by the lunar style Kat should not be outclassed, though.
Another thing we shouldn't forget is that in close combat Ruby is in range for Kat's statsis field, meaning that Kat can at any moment push Ruby in any direction she desires.
In total I give this to Kat. I think she has the control over the battle distance here and can use that and her other abilities to stop Ruby fro making effective use of her strengths.
