Yes and no really it's not structurally stronger but it is more stable has it's cast not rolled, and yes it's precision ground. That said your still correct it's a waste for things like gantry sides etc where ground plate isn't required.!!. . . . Use it for bearing plates and Z axis mostly the rest will be fine with normal plate.
