Personally, fast bowling has always been the most attractive thing about cricket for me. There's nothing finer than watching a fast bowler send one of the stumps cartwheeling away. It's not as if I haven't watched Steyn bowl. Primarily, I've seen him in England, New Zealand and Australia - which, granted, are not his favourite domains. But impressive though he is, I have never seen anything which would make me put him ahead of Marshall, McGrath, Ambrose, Hadlee, Imran in terms of skill and entertainment value. Philander was by far the more skilful bowler in the 2012 tour to NZ, for example and Steyn didn't really have any of those 'game changing' spells (though Philander and Morkel definitely did and even Mark Gillespie). Now, don't get me wrong, I'm not trying to say that Steyn is anything other than a fine bowler, but I'm definitely doing some hard stirring to offset some of the massive overrating that goes on for him.
Watching him in South Africa is a different prospect - he was at times unplayable there.... yet still averaged more than Philander. I can't recall having watched Steyn in India, though I suspect I have. That is the thing that massively stands out to me - his record there is phenomenal.
