Without Kohli’s masterful knock in the final, India would have crashed out. He was the difference and gave the bowlers something to defend. Crazy to take a revisionist turn on a game that was played just few days ago.
Kohli is mentioned along other great athletes in other sports like LeBron James, Ronaldo etc. He has a global appeal unlike the over-marketed Tendulkar.
That's mainly for a few reasons.
A) Social media wasnt too relevant during Tendulkar's career. 90% of his career was without social media. From 2004 to 2010, Facebook was still in its infancy stages and Facebook platform at the time wasn't about making people famous, it was about connecting the world and forming close connections with a group of people you knew.
Similarly YouTube in 2004 to 2010 was mostly the vlogging and vevo era. People would upload highlights, or make funny videos, it wasn't like how it is now where the platform is a global money making influencer machine.
Twitter is the same as in 2006 to 2011 it was mostly a platform for news alerts, not a platform for marketing propaganda and individuals.
Instagram was in its absolute infancy from 2010-2012.
By the time social media became the powerhouse it is today where every platform is a self advertising tool, Sachin had retired, so obviously he'd have less followers and overall less relevance as no cricket fan wants to closely follow the past, and wants to stay in the present.
B) Kohli benefitted from being married to a Bollywood star which massively boosted his pr to global standards, something Sachin didn't have the advantage off.
C) Kohli also benefitted from riding off ove Sachin's PR ironically especially when he broke Tendulkar's odi century record lol.
But to answer your question, I've seen both of them play, Sachin > Kohli in both test and odi as a batsmen no question.
However kohli is better then Sachin at chasing. If batting 2nd in odi, Kohli is a better bat but batting first Sachin is ahead. However in test Sachin is superior in all forms.
