23andme + wegene results in my case show quite a bit a difference. As more and more companies become involved in the business of DNA, would not DNA testing standardization become more paramount than ever? With established standards the perception of legitimacy woul be greatly enhanced. I know
many members feel independent standards can produce more discoveries in the field and may be against such regulation.

In my case it was more or less the opposite results:

Ancestry analysis is an exercise in statistics, that is, you're dealing in probabilities. You can never have absolute certainty, everything is based on "best estimates" and different models will always fail somebody somehow. Even medical studies on the effects of drugs can only use "best estimates": there is always a small margin of error (usually 0.1%, but still, that leaves a possibility).

Additionally, northwestern Europeans have very little genetic difference among themselves, so colonial Americans, who are the bulk of test takers, usually have among the least distinctive genomes. It's not possible for any test to completely separate all French and English people, for example.

There are no magic bullets in ancestry analysis, and there probably never will be, unless you can fully sequence the genome of absolutely everyone in the world and map every segment to an individual town. Somehow, I doubt that's ever going to happen.

Long story short, 100% Ashkenazi Jewish in both, pretty accurate I'd say.

Based on the proceeding conversation, they both could be inaccurate?

Very unlikely.

Once you get consistent signals across multiple tests, you have indications of high probability. The more tests disagree, the less confidence you ought to have in them.

Also, Ashkenazim mainly have high endogamy, so are easier to tell apart than most other populations, with certain ancestrally informative markers. Furthermore both his male and female haplogroups are quite suggestive of Ashkenazi ancestry, which don't directly address the whole autosomal trail, but which do generally go along with the assessment.
