Run scoring is dictated more by bowlers than batters though ffs. It's not even a debate worth having given bowlers have far more influence on where the ball is being bowled than the batters, and the batters have a lot more ground to make up in order to best negotiate each delivery. Conditions can tilt this one way or the other, but generally bowlers > batters in Tests. While it's important to have good batting lineups, generally speaking they don't move the needle as much compared to good bowling attacks. See every great side in Test history (McWarne and co, WI pace battery, etc). If you can't acknowledge this then what's the point of responding to me?
The history is that Hadlee was a far more impactful player than Viv taking everything into account. Hence he's the greater cricketer. End of.
Yes every great side had a great attack, they also had great batsmen.
I've never denied bowlers move the needle more, but you still can't win consistently with out runs on the board.
McWarne had Ponting, The quartet had Viv, Lillee and Thompson had Chappell, Steyn ang Philander had Kallis.
They also needed catching support, because having those great bowlers creating chances without them being taken, means very little.
So while you want to isolate it to a single factor, there was multiple. That's my only point.
As I said I think Hadlee was slightly better, but this gulf that you're imagining exists, didn't.
I'm not the biggest fan or peer reviews, but they are part of any evaluation, and for some reason, possibly because he was from NZ, he wasn't nearly held at the same esteem as Viv.
So as much as ORS is now saying Coronis was right, there had to be a reason besides excitement that Viv makes Crifinfo's and Wisden's teams while Hadlee made neither.
Again, I believe Hadlee was slightly ahead, but to pretend it's not a contest. Every bowler from the era will tell you that he was not only the most difficult batsman to bowl to, he was also the best.
And to Subz point, he did it more places, and more difficult places. If he had retired at the same age and amount of tests as Chappell we wouldn't be having this discussion.
