Tendulkar was remarkably consistent even if he didn't have those top end series he had plenty of very impressive ones.
- 1st tour as teen to Aus with two tons in 92
- Very good tour against ATG Aus attack in 99
- Great tour against formidable Aus attack in 2007
- Near ATG tour in SA in 2011
It's not a huge gulf between him and Viv in Aus.
Only in England is Viv well ahead of Tendulkar. But Tendulkar delivered in more places and against more attacks.
I rate ATG series as one criteria but it's more important for you. Consistency matters more.
Nobody claimed the gap between Viv and Sachin in Australia is huge or anything whatsoever, my claim was
- Viv is better in Australia, which you agree with.
- Viv is better in India than Sachin in the West Indies, which you also agree with.
- Viv is well ahead in England, which you also agree with.
- Viv is well ahead in Pakistan, which is just a fact.
His tours of New Zealand and South Africa are impressive and deserve credit, but they're not necessarily something that I cannot see Viv replicate, 49 in NZ amd 46 in SA is impressive don't get me wrong but it's not like a smoking gun, especially given Viv's lack of chances in NZ and SA. I really think when comparing the away record of two cricketers from two different generations, the countries that overlap should be the first criteria for fairness sake.
now ofcourse, if one has ATG work outside the overlapping countries that's a big factor, but I don't really think Sachin achieved something in SA/NZ to overcome Viv's superiority in the overlapping nations
