Here's some fun calculations for the approximate weight of these Celestials.
Let's assume these Celestials have the density of a human being (since they are metal on the outside and somewhat hollow on the inside). So we can say that if they were 6 ft tall then they would weight about 200lb.
Since Arishem is 2000ft tall then he is 2000/6 or 333 and 1/3 times taller than a 6ft person. Thus his weight should be (333 1/3) ^3 times that of a 6ft person.
So his weight would be about (333 1/3)^3 x 200lb or 3.7 million tons.
Now Exitar is about 20,000ft tall. Using the same reasoning then he is (3333 1/3) times taller than a 6ft person and thus weighs about (3333 1/3)^3 x 200lb or about 3.7 billion tons.
Taking average herald characters then these guys can literally step on and squash them without a fight.
Exitar has a massive, massive advantage over tiamut in size and very likely in strength, he also owned 'The One'
Sounds ridiculous and this just may be my immature mind but I see exitar just picking tiamut up and pulling him in half, or sitting on him lol extremely unlikely
But yeah I think exitar would win though
