Gosh I feel like that’s a tough one! For plot armour purposes I’d presume the casual space marine, maybe the custodes. but given how many vessels of heresy are out in the wild, I could see Necrons being a real ground shaker. Saying that though, I have Tyranids, I feel like they’ll keep eating 😂

I would argue that, because of their creativity, their beliefs, and ridiculously effective makeshift weaponry, Orks would be considered OP.
