There are many advantages to the VA system - I have a family member experiencing it now.  A medical problem poorly treated by his civilian doctor is being more thoroughly addressed by his recent visit to the VA.  His civilian doctor did not prescribe the correct dosage of medication for 3 years.  His civilian doctor did not know that his symptoms are tied to Agent Orange exposure; the VA doctor looked at his service record and recognized a connection right away, and ordered relevant tests.  They are also reviewing his case for a possible increase to his service-related disability payments, authorizing daycare services, and providing 28 days a year of respite to his caregiver.  

The Choice program is appropriate to provide care when the VA system is unavailable or unresponsive.  It is not a good substitute for the VA system entirely.
