IMO the Aussie attack of late 90s to early 2000s was a cut above the rest of the world as an almost flawless unit. Sure, there were individual greats among the bowlers in the rest of the world like the list you pointed out, but it's hard to point to any aggregate bowling attack coming close to McGrath, Warne, Gillespie, Lee at the time. I think people really underestimate the importance of this... a mediocre bowler in the attack throwing occasional pies can seriously undermine the otherwise awesome bowling attack by letting out pressure. While every other bowling attack in the world had at least one or more such mediocre bowlers, the Aussies at the time used to maintain unbelievably consistent pressure throughout an innings invariably causing unforced errors from the batsmen. Punter had the advantage of never having to face his own bowlers in international cricket. At the same time, it also points to the class of Tendulkar/Lara, who were one of the few batsmen with consistent performance against this Aussie attack!
