What???

In another thread, somebody posted that Arnel's vocals were more raw and powerful than Perry's. Still trying to wrap my head around that one. Any examples?
Listening/watching this youtube.........some of the most raw, powerful and passionate vocals. Shaking my head, sorry just don't get it.....maybe it's Perry's tone/timbre or maybe it's all in the delivery. Emoting is all about feeling the song you're performing...........just can't see the comparison....nobody "feels" a song quite like Perry.
