Why is a rook better than a bishop?

Can you elaborate on why some might consider a rook to be more advantageous than a bishop in the game of chess? Is it due to its unique ability to move in both horizontal and vertical directions, providing more flexibility and range of attack? Or does it stem from the potential for faster development and control over critical squares on the board? Could you also discuss any scenarios where the bishop might actually be more useful, considering its long-range diagonal movements?
