Mohammed Kandeel has a really very beautiful voice. But let's be clear it is not better than Halim otherwise he would have been more popular. Besides, of course, Um Kalthoom will pick anyone but Halim because she was threatened by him. I'm always puzzeled by those who refer to the strongest voice. The point is not so much strength in the voice but rather an effective one. Halim has a rare combination of many charactersitics including voice, looks, emotion, intelligence, etc that no one else ever had before or will have in the future. My humble opinion
