She would top the life out of him, absolutely, if only as a power move. She likes bringing people's ego down when she finds them too arrogant, and Magnai has a massive superiority complex. He's, deep down caring enough, though, that his personality doesn't repulse her entirely. Physically, he fits her taste and could at least maybe handle her for some time before giving out. She also likes that he's a bit of a simp, as worship/ teasing/ denial is a fairly big kink for her.
