On who might be the better bowler I think you could argue either way. However, as a new ball bowler there were many as good as McGrath (Lillee, Marshall, Garner, Hadlee, Imran, Donald were all as dangerous against all opponents). As a leg spinner, Warne was without challenge.

McGrath may have won more test matches (and I think he did) - that's the nature of playing cricket with a new cherry every time, the game is really set up for the pace bowlers, but Warne really was special. OK India mastered him - it is a pity that the first two tours of India he had shoulder and finger injuries. His final tour of India he had the disappointment to miss the final test where he's have got his 10 in the match.

In 20 years, people will not be talking about McGrath. Someone will have risen up to take his place. They will still be talking about Warne.
