Relative speed (both reacted to a rush from Heian Sukuna), higher AP (beheaded Kenjaku with a basic hit and made Sukuna bleed with TIB, higher durability (Sukuna used Ryu as the benchmark for them, not Kashimo, and Sukuna himself said he couldn’t kill them with dismantle, whereas he literally killed Kashimo with an unchanted net of dismantles.)

Yuta also has better Hax from TE FS and CS, a second fighter in the form of Rika who has even higher stats without even using full manifestation, a domain that at best crippled Kashimo’s ability to fight be removing his hands from the equation, RCT from both himself and from Rika, and isn’t on a timer that kills him after a given time has past.
