I don't think I've ever seen anyone with the former view, at least not in an exact sense. Mind, I don't usually seek them out either.

Though wouldn't Reiryoku make more sense over Reiatsu? Reiryoku is generated from the soul of a being, its a very internal energy (And Reiatsu is just an expression of it). It might be just because I tend to work on the idea that Shinigami focus on Reiryoku, Hollows/Arrancar have a focus on molding their Reiatsu and Quincy have a reliance on Reishi (Mixed with their Reiryoku).
