Which of the Genetic Tests is Most Accurate?

[Ewigkeit]

For me at least, GEDmatch is yielding very different results than the commercial tests did. Specifically it says I have much more SSA admixture than Ancestry/DNA tribes did. I'm wondering what accounts for the difference and which test is more accurate. Are the GEDmatch tests better at probing "deep" DNA? Or are they more liable to false positives?

They are not very flexible if that means anything. Each calc gives me quite different results because I am mixed with so many things.
