In WWE's part, was it a good decision to put giants over greats for The Undertaker to face at Wrestlemania?

Like Giant Gonzales over Hulk Hogan at Wrestlemania IX. King Kong Bundy over Bret Hart at Wrestlemania XI. Big Boss Man over Mankind at Wrestlemania XV. Big Show & A-Train over Eddie Guerrero & Rey Mysterio at Wrestlemania XIX. And Mark Henry over Kurt Angle or Chris Benoit at Wrestlemania XXII.
