Your comparison of bowling is not practical at all.
Bowlers do not have to be individually ahead of their opponents. They just have to contribute to 20 wickets. Indian bowling line up of last 50 years is world class and will deliver 20 wickets anywhere. You clearly missed the part wgere j said guys like Agarkar, RP Singh, Irfan Pathan and Sreesanth have won tests on their own in SENA
Australia is not at par with India batting wise. They are not as bad but not as good. India is in an elite of its own batting wise historically speaking. Not just last year's but last 150 years of Cricket combined.
Australia kills India batting wise. For test cricket, let's rank the best Aus and Ind test batsmen
1. Bradman vs Tendulkar. Bradman wins. Almost universally considered the GOAT
2. Gavaskar vs Smith. Let's call it a tie. For me Smith wins but arguments can be made either side
3. Chappell vs Dravid. Chappell easily. The bloke who excelled vs everyone he played against, in particular vs the mighty WI pace attack is better than a man who dspite playing some great innings, was generally mediocre in pace-friendly conditions
4. Waugh vs Kohli. Kohli could improve significantly, but to this stage in his career Waugh has just accomplished more, with an incredible well rounded record and some clutch innings that Kohli could only dream about. His record vs the top teams (SA, WI) is ridiculously good
That isn't that embarrassing for India, but the following ones will be. Who is the next best Indian batsmen. With all credit to them, Sehwag, Laxman, Hazare, Merchant, Viswanath, Pujara and Vengsarkar have nothing on Border, Ponting, Harvey, Hayden, Trumper, McCabe, Clarke and Hussey.
Alternatively, we could do a comparison by decade, looking purely at their accomplishments within that decade and selecting the best bat from that decade:
Note I have looked at Indian FC stats to see if they have any comparable players during this time
1910's: Trumper
20's: Macartney
30's: Bradman
40's: Bradman
50's: Harvey
60's: Simpson
70's: Gavaskar. I personally believe that Chappell was better than Gavaskar during this time period, but I have to give India one
80's: Border
90's: Sachin
00's: Ponting, much better than Sachin within this period
10's: Smith
Using all metrics, Australia have produced greater test bats than India. WI as well, and England would run them close based on their dominance in the 1st half of the century.
Stop being so biased. With statements like India > Aus in the last 50 years, Shami is an ATG and Dev > Imran, people will stop taking you seriously
