This is hardly the best sample from Tendulkar's peak. Here's one which I put zero effort into with a 6 run lead over the next batsman with 6000+ runs on a Jan 1 to Dec 31 basis. I'm sure I could get one a bit better better if I put in some effort:

This is Viv's 6 year peak where he averaged 10+ runs more than anyone else:

Here's Sobers with a nearly 12 run advantage over everyone else across 11 years and 5500 runs (1958-67):

The point being that while Smith is one of the greatest batsmen ever along with the likes of Tendulkar, Sobers, Viv, Hobbs, Hammond, Headley etc. He is not some never ever seen before freak even in terms of peak batting. Given that, unless Smith goes on for about 50-60 more tests, I'd rather have someone like Tendulkar. Sobers or Hobbs over Smith as they had a 20+ year as an international batsmen while also being much better than anyone else at their peak.
