It is my understanding that Vulkan and Ferrus Manus are considered the largest and strongest among the Primarchs, excluding Magnus the Red who is essentially a psychic roider. Is this correct?
Are there any specific mentions in the lore regarding which of the two is taller or possesses greater physical strength? If possible, please provide the relevant sources or citations.
I have come across conflicting information: some claim the distinction is too ambiguous to determine a clear superior, while others assert that Ferrus was taller, or that Vulkan was both larger and stronger. I am currently looking for clarification on this matter.
