I think in history of test cricket, many players have done well at home, but very few have done well away. Then you have best of the best who have done well against good teams away. That's the toughest test of any player because even ordinary looking home teams puts up a good fight and if you are playing against better teams away then it gets tough for even greats to stand out.
IK is simply the top 3 test all rounder for me. As a bowler alone, he goes much lower. Not sure exact spot, never thought about it,
As quick short cut to see quality of players - how well they did when playing away.
Taking all non-minnows during IK's career. we can see who did what in Avg and SR, I am not sure about quality of cirkcet in older era so limiting it to starting from 60s and ending it at IK's retirment.
IK - Away Avg 26-27 and SR 60 plus
Among his peers,
Garner, Holding, Marshall, Hadlee, Roberts all averaging sub 24 with SR sub 55. You have Lillee 24 avg with 55 SR. No one talks about Alderman and even he avg 25-26 with SR sub 55.
Not saying that Alderman is better than IK, only sharing why I don't rate IK that high among ATG bowlers.
Many fans talk about biased home umpiring and ball tampering. I think it muddies the discussion. Looking at only away performance for all player puts them at the same level field. No need to discuss if umpires were more or less biased in some country. Everyone faced the same away umpire in this list and had the same disadvanatge. It's a level playing field for all players.
How many greats in history have combination of away Avg of 26-27 & SR of 60 against non-minnows? IK has that.
I am hard pressed to name many. Yes, I am aware of some great series by IK, but peak and non-peak both are part of your career. Look at two best bowlers in his generation, Marshall and Hadlee. How far ahead they were.
Marshall/Hadlee - Avg 21-22 & SR sub 50
Many others like Garner, Roberts, Ambrose with sub 24 Avg & sub 55 SR
Then in last
IK - Avg 26 & SR 60 plus
So I don't know the exact place to rank, I never thought about it. Among the best as all rounder, but surely not among the best bowlers. It's not an elite bowler's output. I know he was ordinary initially, and great in middle and did not bowl later. But that's his collective output as a bowler. You don't get rated only for 35 best tests in your career. Marshall, Hadlee, McGrath, Ambrose, Steyn all are surely better. Bumrah is likely to join the list. Then you also have Roberts, Donald etc.
Having great home record is good, but it does not allow us to do apple to apple comparison because that's not level playing field in older era and we get into discussion of tampering, umpring etc being different in differnet venues. But away was level playing for everyone. Also, players like Marshall, Hadlee, Mcgrath, Ambrose, Steyn, Donald, Roberts etc had gun record at home as well so it was not as lop sided as IK. IK has like 20 avg and 50 SR at home against non-minnows but it jumps to 26-27 avg and 60 plus SR away. No one else had such disparity. Out of these two records, only away record can be compared apple to apple for all players in that era. Even across era, away is a far better short cut otherwise someone like Jadeja might get rated as an ATG bowler.
May be near 8-10 spot due to great record at home. Some may argue for even lower, don't know. Certainly not a candidate for top 6-7 test bowlers. We have to torture the logic to make the case. No top 6-7 test bowlers in such a long history should have combination of avg of 26-27 away with SR of 60. True quality of bowlers can be easily judged based on how they did away in all eras.
When all said and done, actual performance ( low avg and low SR ) counts despite all other noise. That's how you take 20 wickets cheaply and win tests. Greats of the game have done it in away conditions because that's the toughest job in test cricket. Across era can have variables but you can still see who stands out in their own era and by how much. IK stands out in a negative way in Avg and SR when playing away.
I shared my opinion with thoughts behind it. I will leave it upto you to make up you own mind.
Away performance of IK compared to peer group:
