A better Prime Minister – Nehru or Patel?

Lord Mountbatten the last viceroy firmly believed that Nehru was unfit to rule India and would not be able to handle issues like the partition and departure of the British administration. Even the Congress committees did not support Nehru. This is when Gandhi stepped in and asked Sardar Patel not to contest. Was this a historic blunder? Would Patel have been a better Prime Minister?
