As far as which is ‘best’?
Well, that would be a matter of opinion which will vary from player to player.
Each person likes to utilize skills that they enjoy and find successful.

Is Graeme Swann now the best spinner in world cricket?

he was 2nd in terms of most Test match wickets in 2009 – only Mitchel Johnson took more. He has now proved he can perform against the best with 9 wickets in the match against S.A.
there are few ‘great’ spinners now in the international game – Vettori and Harbhajan are his main competitors I guess.
