As for the Garner Vs Lillee debate ,it is very tough,a bit like the Ambrose vs MCgrath one.
And picking one over the other is equally as tough.
I voted for Garner weeks back ,but by the very very slightest of margins.
Garner was the more miserly of the two ,extremely accurate and used his height to his advantage getting bounce and being fearsome in that respect.His go to ball was the yorker ,and he got not only tailenders but established Batsmen like Botham ,wessells ,and Kim Hughes in lot of trouble with his bouncer yorker combinations many a time.Contrary to popular notion he also got some movement of the wicket ,specially when the wicket was green ,like in newzealand according to the reports of his exploits. He was also despite being a extremely scary bowler a gentle human being with a smile always on his face.
Lillee on the other hand was more aggressive ,the quicker of the two by a slight margin but less accurate.His USP was swing in the air ,Which combined with pace was lethal.His action was more refined than the rawness of Garner ,so was his is run up. What also shows the contrast in the two bowlers style is that Garner got a lot more batsmen in terms of ratio bowled or LBW,while Lillee got a more in terms of ratio caught and caught by the wicketkeeper usually rod marsh.
Lillee also like a stereotype fast bowler was more of a showman and more controversial .Though at the same time he was a extreme hard worker who bounced back from a very serious career threatening injury eraly in his career.
Both were greats ,so it extremely hard to split with decisiveness like the Mcgrath-Ambrose one .But one thing i would say that in all time stakes i would have Mcgrath and Ambrose ahead of the two in this thread by a narrrow margin.
