A consistent grievance of directory operators is dealing with automated or otherwise low quality submissions. Therefore I'd look for apps that provide strong options for blocking, filtering submissions by rules, bulk delete, automated sorting, etc.

Other features that matter:

• Good record of support
  
• Sophistication of admin panel: # options, granularity, ability to automate routine processes
  
• Clean, easy to modify templates
  
• Search engine friendly URLs
  
• Breadcrumb trail navigation as element of site nav
  
• Multiple admin options for handling listings: Featured, rotating, sorting
  
• Integration with payment processing if you plan paid listings
  
• ?
