No. Kane's batting was nothing special in WTC 2021. He scored only 50 runs in first inning and had to chase 150 in second inning, NZ had an advantage that Jamieson and Southee scored quickfire 30-40 runs which made the difference and Jamieson's bowling was better than anyone else. That was the only difference in that game.
Kohli has won POT award in 2014 and 2016 WC as well and leading run scorer in 2022 WC as well smashing the Pakistani bowling attack flooded with 155-160 kph pacers for 48 runs in 18 balls in winning cause. Kane can actually only dream of such feats.
Kohli has also hit some outrageous hundreds in Tests in England, India, South Africa and Australia, which again Kane can only dream of.
Both Smith and Root have won test matches in India but Kane hasn't won even there.
As a batter, Kane is not even half as good as Kohli who is basically not even among top 5 Indian batsman of all-time.
