Quality bowlers do exist. Especially in test you see stark, James Anderson being xompletly different beasts. It's just the 2 new balls have made it ridiculously easy to score 100's.
Ik their different formats and being good in one doesn't translate to being good in the other case in point yk
But odi use to be the most difficult format since in test you can take time and in t20 the one ball doesn't become soft and old quickly enough.
Now odi is the easiest format to score in. T20 and test are harder.
Not taking anything away from kohli, he is beyond class and easily in the patheon of viv, sachin and others, no doubt.
But test is the best way to measure them due to old systems still in place.
Both bats played in similar conditons ut Sachin faced slightly superior bowlers and averaged better then kohli.
Imo Sachin > Kohli > Pointing as batsmen
