*I think its John Williams.... * *But when it comes to versatility, the WORLD knows ARR us No.1, coz he can compose in any genre under the SUN..* *He also CREATES genres (Eg: THEE THEE/ DIL HAI SANAM from THIRUDA THIRUDA/ CHOR CHOR)......*
John Williams is very OLD (76)..... So he has become No.1 ..... ARR is just 41( A time where John Williams got early breaks).... So ARR's career is NOT even HALF-WAY..... so ARR has a LOT of time to be the No.1 composer in the WORLD!! I bet he reaches that position in another 6-7 years!!
