trying to keep the thing serious, I think we have all seen just about all the stats and all the various possible inferences one can draw from them and honestly, just like the Sachin Vs Lara debate, AFAIC, there is very little to split between the two statistically. The men have NOT played in similar conditions all the time and there are reasons that can be given for each and every one of their successes and failures...
At the end of the day, for me, Warne is 5% more likely to bounce back after a pounding and produce a great match changing spell out of nowhere than Murali and Murali is 5% more likely than Warne to NOT have an off day.... It comes down to your personal preference... For instance, in selecting a World XI, if I pick an attack of McGrath, Akram and Ambrose, then I would definitely want Warne as my spinner because I want that 5% more of match winning ability than the 5% extra consistency.. But if my attack was Akram, Marshall and Younis (at his peak, that is), then I would want Murali simply because in that case I would value that 5% more consistency higher..... It comes down to personal preference and I don't think there is any real way one can be claimed to be better than the other unequivocally...
