Steyn has a notably better average and SR and was simply more penetrative in the time he played. Longevity only really counts if you are more or less in the same level of effectiveness as bowlers, just that one played longer.So , better longevity.
But it's not the case. Warne was more condition dependent, more innings dependent (basically was only worldclass for 3rd and 4th innings) and more easy to get on top of.
