Who's the best spin bowler ever? Muttiah Muralitharan or Shane Warne?

yeah that is why Shane was popping pills, which his moma gave him......wink wink! In reality he should have been banned for life, but he is still playing. Murali was born with that bent arm, he cannot stretch his arm fully. All Yahoos who cannot beat him, complained to ICC. They did all the mechanical testes and everything came negative.
