A comparison chart's been made a month ago to keep track of lucky and unlucky moments this year and evaluate race results between the two on merit alone.

Leclerc had 17 bad luck moments in 15 races, Sainz was lucky 11 times. Q was also harder on Leclerc than Sainz.
On merit, races ended 11-1 for Leclerc. That 1 was France, since even with reverse it's hard to see Leclerc finishing ahead of Sainz.
It's not even close between them.
