Other than a home loan guarantee some 25 years ago, my only VA experience has been with education assistance programs. The payments came fairly promptly, and were sufficient for my needs at the time. I don't qualify for treatment at a VA medical facility, so I can't give any input there.
I've never been to a VA hospital, so don't know. But I've never heard anything good about them from people who have been there. I go to normal doctors and use tricare military health plan.
Partial impetus for this poll:
It's also a pure example of “socialized medicine.”
In this link, I did try to find something relatively neutral.
