Question

In all sorts of places I’ve heard very effusive praise about the reasoning of the Rashba, and about laboring over a little piece of Rashba. I don’t really identify the uniqueness, but that’s not saying much, because my understanding is very limited. Does the Rabbi identify something special in the Rashba (as compared, say, to Tosafot, the Raavad, Nachmanides, the Ritva, and the Meiri)? And perhaps does the Rabbi have some clue toward a characterization that could help me understand?
