While both graphic design agencies and freelancers have their pros and cons, hiring an agency comes with some very distinct advantages.
The combined experience of an agency is just a big advantage for a customer as graphic design agencies could have teams of staff looking after having a job, which means there won’t be any threat of sick staff postponing a deadline. Agencies will also have more experience than freelancers in dealing with large clients and accounts and will most likely have a long set of satisfied clients. Another big benefit of an agency is that because of their size, the agency teams can come up with a broader selection of ideas than a single freelancer can. A style agency could have access to higher resources then the freelancer with an increase of extensive industry contacts and better equipment.
The real benefit of hiring an agency is that you generally know what you’re going to have, while freelancers are far more unpredictable. I don’t speak for several freelancers but in my experience the majority are after big chucks of money and often don’t take into account the client’s must the same level as an agency.

Graphic design agencies hire accounts people to manage clients and manage expectations while a freelancer is significantly more than likely to be a designer in mind and are usually not good at building client relations. This can cause missed deadlines and unreliable work ethic. I don’t speak for several freelancers obviously but there might be no doubt that agencies are better organised.
