Is Don Bradman or Sachin greatest cricketer of all time?

Is Don bradman or sachin the greatest cricketer of all time?don bradman having a test average of 99.94 is considered to be better than Sachin Tendulkar.Most people say Bradman had to play on tough australlian and english conditions while Sachin Tendulkar played most of his matches on flat indian pitches.In addition to that Bradman's test average of 99.94 is way better than sachin's test average of 53.86.Having said all these still can we consider Bradman better than sachin?First of all,everyone's theory about flat pitches in india is nonsense.Of course in india ball won't seam or swing much but what it does is spin.Its more difficult to bat when ball is spinning.One thing we should consider is that Don Bradman had't played in india at all.Seeing the way australlians,english players and south africans struggling in india we have to assume that Bradman won't be as dominant as he was in aussie or english conditions.Other thing we have to take into consideration is that sachin has scored close to 16,000 runs compared to Bradman's 7000.That means sachin scored more than twice the amount of runs sored by Don Bradman.Not to mention the fact that sachin's supreme one day record of 18000 runs at an average of 45 makes him the best batsman of all time.Sachin ability to play on bouncy and seaming tracks can never be questioned after watching innings he played on Sydney,Capetown and Trent bridge.It is a fact that sachin can play on any tracks while we will never know whether Don Bradman can play on turning indian pitches.
