Wasim himself said bumrah is better than him though. Waqar is Inferior to wasim.
Not everything is about longevity. Impact matters. Bumrah had much more impact va strong teams than waqar ever did. Waqar was bad vs australia and India. India being arch rivals even If they weren't a top side then
Bumrah is not better then Wasim not even close.
You could say Bumrah is more consistent as after injury he seems to be an even better bowler whereas pakistani pacers after injury are done cases and wasim later in his career was inferior to Bumrah however their isnt a single bowler better then wasim akram in his prime or when he's onsong in general.
Mcgrath and Garner are exceptions however mcgrath and Garner are lethal because they were capable of bowling the perfect line and length in the exact same area at the exact same pace for over 60 deliveires in odi and upto 27 to 30 overs in test, Which is insane.
Since even Bumrah and wasim and waqar would eventually give half volleys or loose deliveries or full tosses or half trackers, it's extremely difficult to bowl the right areas 24/7 like those 2 did.
But wasim akram in prime has deliveries which are beyond stupid and nonsensical and he was able to do so without ball tampering in play. Literally one of his deliveires pitches outside the 3rd line and was going for a wide and it swung in all the way into offstump, like how on earth does one even play that?
This dude truly was the king of swing and the likes of prime steyn, Waqar or others would water their mouths at akram.
In the world cup they noticed that bumrah swing is significantly greater then all 3 pakistani pacers combined, but I guarantee you that's nothing compared to wasim.
No one could bowl those killer inswingers, outswingers, and a ridiculously lethal reverse swing like he could.
Bumrah does not compare by any metric, Bumrah can only be appreciated for longetivity and consistency but he is far far away from the likes of mcgrath, Garner, Wasim.
Bumrah vs Waqar younis is debatable though.
