user: Who is the greatest cricketer of all time.

assistant: There are many cricketers who could lay claim to the mantle of greatest cricketer of all time. Cricket is a bat and ball game that has been played internationally for nearly 150 years. Two names are often suggested to be the greatest. Sir Donald Bradman and Sir Gary Sobers. Bradman for having a batting average that will never be beaten and Sobers  for being an all rounder who was outstanding in bowling batting and fielding
Both of these players would be picked in any best test team of all time.  The only caveat is that neither player excelled or played in the shorter forms of the game.

user: What is better Android or iphone

assistant: The answer to whether Android or iphone (iOS) is better is really down to user preference.  The Android operating system is more open and is used by multiple phone manufacturers catering to different tastes and price points. iOS is a more closed system only utilized by Apple, which tends to be more secure and efficient. However, this offers fewer choices of handsets for purchasers.  Ultimately the choice between Android and iOS will come down to whether the purchaser is willing to pay the price of an iPhone or prefers the handsets offered on Android.
