Idk how this Kohli vs Sachin debate has started once again. It's stupid to compare players from 2 different eras. You can never compare players from different era.
STAT: The last instance of two (or more) South Africa batters registering hundreds in the same Test innings was against India in Visakhapatnam in 2019 (Dean Elgar 160 & Quinton de Kock 111).
