Ancestry has Italian and Greece at about 12%, but 23andMe does not show any Italian and/or Greece in my results.

23andMe shows a small percent for French and German. Ancestry does not show any French or German.

23andMe shows a large portion as NW European. Ancestry does not show any NW European. Ancestry does show about 10% as Western Europe.

There are other differences as well, but these are the most significant.
How do these differences in results from the two companies relate to what you know about your ancestry by traditional means?

Perhaps you need to think about it.

Do you have anything of value to contribute to the topic other than judgement?

I have contributed a lot to the topic so I really don't need your non contributing judgments.

People should know what they are wasting their money on when using the direct-to-consumer DNA companies.

Here is a good read from a person who has used 4 different direct-to-consumer DNA testing companies.

MY DNA RESULTS FROM 4 COMPANIES

Here is a comparison between 23andme and Family Tree DNA.

And last but not least:

How accurate is 23andMe?

I had a gg grandfather who was very French and another who was from Germany. I have no known Italian or Greece in my family line. I have some Swiss in my background and knew about the Irish and English.

I don't know how Ancestry comes up with their numbers (I haven't used them) but 23andMe gives three estimates of ancestry. Unfortunately, most people only read the "speculative" estimate which is beyond ridiculous. IMO, you might as well toss a coin. Science is not yet at the point where ancestry, particularly on a country level, can be determined with any degree of certainty.

My argument regarding the validity of the results is limited to 23andMe's ability to identify gene variants that are associated with specific medical disorders and its matching of relatives.

Ancestry.com calculates ethnicity estimates by running 40 different analysis and then averaging the results out. The final percentage they give for a category is the average, and then they also provide a percentage range for each category, which tells you the lowest and highest percentage you had for that category among their 40 analysis. Much like at 23andMe, most people just look at the final percentage, not the percentage range.
