it's a combination of the two
kayn is more powerful than the average dude and rhaast is a bit weaker than the average darkin
also varus comments on "ionian" vessels being too strong + ionia is refered to as the first land now in cinematics
theres a chance that ionians are just much stronger spiritually
theres also a chance xin got taken over this quickly because he surrendered + he was begging zaahen to take his body
you can even see the dude being somewhat sad as xin disintegrates infront of him
