I used Ancestry DNA
The geographic sites match up pretty well to our own known family history.
The most impressive feature is that we've had about a dozen of our family take the tests and they've nailed the relationships.
The long lost uncle (no one knew about) showed up as third in my relationships behind my own daughter and my aunt (Mother's sister) and ahead of my first cousins. His daughters show up as cousins.
You can perhaps question the ethnicity factor but the relationship factor seems to be quite accurate.
