By herself without Takeru, armored Ushi will be more loyal to her Master, and won't help Sieg escape just because, so Black Faction still keeps Siegfried. Achilles might note how her attacks can harm him, and suspect her possessing Divinity.
As I said earlier, she's loyal as long as her armor's intact. But once her armor breaks, she becomes unpredictable, so both factions will have to team up against her and Ox-king instead of Dracula.
If Takeru's around, he's more flexible than Siegfried, and Gordes doesn't have to worry about glaring weaknesses. So it's more firepower for Black faction, at the risk of the Rider going berserk.
