100%. Mitchell Starc is better than Mitchell Johnson.
If you want to go way back 5-6 years then of course Johnson was better because Starc wasn’t born in cricketing world then😂.
But After the arrival of Starc, he is the best bowler in the world. I think he is better than Bumrah too ( I’m thankful that you aren’t offended.)
He can clock regularly 150 kmph and can produce cracking Yorkers as well as terrific bouncers to make batsmen fear.
Whereas in current, Johnson isn’t in the top 30 list and not in top 50 also. It’s because he has past his prime. He was also best bowler in his era but this is the era of Mitchell Starc , Jasprit Bumrah and Rashid Khan.
Hope you enjoyed the answer.
