Wegene and Gedmatch vs. Ancestry Dna and 23andme

[Jpressle]

Have been meaning to post this for some time. My 23andme and AncestryDna results are similar in the break down of my African ancestry to European. However, Wegene and some Gedmatch tests such GedrosiaDNA-K3 and have what I think are significantly different results. Would like to know if any here could offer a reason for the difference or which is more accurate. Also, any insights as to why 23andme found twice as much Ashkenazi admixture as all other test, 10% to about 5% or less.

All I can say is that, on WeGene, my African is also a bit smaller than on 23andme (15.31% v. 16.5%). I'd trust 23andme more, as their autosomic ancestry tool is said to be the best there is among the commercial testing companies.
