I like that they are very professional in their work ethic which helps me to trust them with my personal information such as medical records etc! They do not have much history so it's hard to tell if this will help or hurt your situation but i would go for access because you're going into uncharted territory when choosing another agency/firm.
There really isn't anything bad about working through access at all though there has been nothing too mention either way except some minor issues here nthere (but no big ones). You get what u pay for right? Well don't expect miracles from cheap firms just be aware of how good companies charge per hour vs cost versus quality services provided by each firm. Make sure ur getting value for money otherwise its an unfair business practice -_-.
