Sachin only had Mongia who provided some support in that innings, while Lara had 3 batters who chipped in with useful 30s. I would still not claim that Sachin's inning was better or on par, just pointing out at the variables we always miss when we are so obsessed with stats and certain conditions without really looking at so many other factors that impact each game/innings.
Also, as mentioned by
@subshakerz that "the innings are close. But one gets featured in the top five of all-time, the other doesn't make the top 100 most times. "
Overall, stats-crunching is good for the romance of it, but a lot of times it create a very unclear picture of things.
