Which is the better Format Of Cricket?

Recently a question is arising that which format of cricket is better between ODI and 20-20?Without any doubt,latter is more popular but lot of cricket experts are blaming it as they feel this format is ruining the greatness of this game.
Twenty-Twenty has a very interesting format.Actually When One Day Internationals came people used to find them very attractive and as it was of less time compared to Test Cricket,so viewers started enjoying it even more.Same thing applies now to the Twenty Twenty Cricket,it takes less time compared to One Day Cricket.The format is interesting is people just love to see those big sixes.They do not require to spend a whole day to watch the game as they can easily catch it after the day's work.I must add that Indian Premiere League has surely done great job to make this format popular.
But I think the disadvantage is for the bowlers.The pitches are made such that more runs are scored.Viewers just want to see more runs and the bowlers are beaten up a lot.So,I think there should be a proper balance in the pitches so that both batsmen and bowlers be able to take advantage from the pitch.
