T20 cricket declared result earlier and also a lot of entertainment and money is available in large amount. But we compare about T20 cricket to one day cricket there is not enough time to analyse the batsman or bowler in T20 cricket because it can possible one player cannot analyse within a match but one day cricket is one of the cricket is to analyse who is best batsman or bowler (one day player can perform well in T20 but there is no chance of T20 player can perform in one day because there is need of defense and they can be not well defenser.
