The FMA - headed up by Sean Hughes - opened in April.
CEOs said both agencies appeared "under-resourced" and "needed more budget." Though it was too early to form a judgment on the FMA, they nevertheless rated the authority's performance marginally head of the SFO.
It is clear from chief executives comments that there are bugbears in the FMA's relationship with companies.
Among them:
* "The FMA is virtually invisible for mum and dad investors and has done nothing to address the fundamental issue of how to create confidence and appetite for investment in the capital markets - they do not understand who their customers really are!"
* "I would like them to spend more time on clarifying the very grey rules rather than bashing companies in the courts, particularly in the area of continuous disclosure which is ripe for what constitutes good practice."
* "The FMA is wasting time and money with weak investigations that have no merit to send an unwarranted message. Complete waste of time at the moment. Minutes of research recently would have saved hours of work and money on an investigation."
It's early days yet for the enforcement agencies - but clearly they have work to do before they gain the full confidence of company chiefs and market participants.
