Now my friend who is currently near completing his ACCA explained it pretty easy & simple
He said that Chartered accountant is a Thief he thefts & takes advantage of the of the weakness of the Laws legally hence he saves more money for the company & a costmanagement accountant have no relation with Law he just manages the cost to the optimum level hence decreasing the cost for company
you can decide it yourself who is more good for the company?Thief or Cost saving
