The Ashes - is it the only real thing?

For all their purported hatred for the 'Poms', the Aussies and the English have a 'mutual admiration society' going.

 

Suppose the England team beats Bangladesh, immediately their media will start talking about how this team could be basis of their next Ashes challenge indicating that 'The Ashes' is the only series they are concerned.

 

Unfortunately, this affliction seems to have spread to Australia. Their bowling coach, Troy Cooley says that the current Aussies bowling attack is as good as England's 2005 Ashes winners, implying that the England teams bowling attack for the 2005 Ashes is the bench mark for all bowling attacks to emulate.

 

Which begs the question, do you consider 'The Ashes' to be, in terms of quality and competition, the best Test match series?
