Well I don't agree with that at all, and those you named - McGrath, Wasim, Donald, Walsh and the Pollock who was really, really good (rather than merely good) against anyone else (ie, 1995/96-2001) - also had good-to-excellent records in Australia. Who are these outstanding, top-of-the-tree bowlers who failed there and succeeded in India?
Gilchrist post-2003/04 wasn't much crack - certainly no better than Dhoni and probably worse, though yes, better than Patel or Karthik - and the Indian middle-order has by-and-large been comfortably better than the Australian one. Hayden and Sehwag, little challenge though they may have been posed by particularly good attacks, have been equally prolific and while Langer was indeed far better than all other openers India tried until very recently with Gambhir, that's one place out of seven.
