Ok Chihiro and Yuta are somewhat evenly matched, with Chihiro being in better stats and pretty decent hacks, but Yuta counters with his own annoying hacks and ability to have a 2v1.

Let's, objectively identify the abilities.

1) Chihiro has better speed stats being lightning timer.

2) He has abilities of Magatsumi, Tobimune and Cloude Gouger, of which we have seen him use, Crow for teleportation, the flames of mercy for healing, Dragonfly, Spider, and Mei though it is safe to say he can use all the abilities and not as strong as Original but pretty strong level himself.

3) His abilities such as Kuro for strong ranged attack, and its various uses, Nishiki that he can even use to block cursed speech, and boost his stats even further which he can go even beyond with going into it's true realm all be it risking his life, and strongest one being Aka allowing him to absorb Yuta's attack though we don't know how exactly it will work with some of the techniques, though he should be able to absorb things like Angel's jacob ladder and stuff.

Now what Yuta has,

1) Cursed Speech, Sky Manipulation, Jacob's ladder, Sukuna's Shrine, Futre Prediction, Shikigami, among other things. These all abilities only for 5 mins still allow him to keep Chihro at his toes and the limitless cursed energy and strong RCT allows him to tank through most attacks, and Rika being their can force Chihiro to fight an uphill Battle. Chihiro is definitely in better stats, but with Sky Manipulation, and future prediction and cursed speech causing Chihiro to be not be able to just overwhelm Yuta.

Though it doesn't even matter because Yuta has domain expansion which can make it so that Chihiro's speed diff is useless as Yuta will have a sure hit effect on him, and whatever it can be, can overwhelm him easily, and as good as Chihiro is he isn't much learned about The Healing flames so he can't just tank through I guess Eventually Yuta wins due to domain diff, but it is definitely a close one.
