About the "more prone" part...how would you describe Boo's abnormal Chi? We know he's a magical monster, but he's composed of two Gods that are basically of the same nature as Kaioshin.
Considering Rou Dai Kaioshin hypothesised something as associated with the Kaioshin as the Potara's magic could be undone by the nature of Boo's body without contradiction from Kibitoshin as well as the abnormal effect Dai Kaioshin had on Boo, I'd say his magical nature is far different to the Kaioshin regardless of their presence within him.
It didn't take long for everyone to become accustomed to his Chi despite the abnormality.
That may not be the case, given this statement by Toriyama:

"The frightening thing about Majin Buu is his unknown, unfathomable power. Whether it's actually not that much, or really stupendous, Majin Buu himself probably doesn't know the answer."
Sounds as though it's impossible for characters to tell how powerful Boo really is from sensing alone based on that, with those that offer a benchmark to him or others having to gauge him through his movements in battle.
