Why you should get AncestryDNA over 23andme

[Pennywise]

People who rely on what dna testing company display as a results don't understand shit about genetics.

The only important thing is the raw data. A company that does not provide raw data should be considered garbage. As for the quality of the raw data, from the most usable to the least, it looks like this:
23andme>Ftdna>AncestryDNA

you must be a genealogist.

Ancestry and FTDNA test more SNPs, it's useful for deep clade tests (ydna/mtdna) and genealogy. 23 have their own custom selection of SNPs more relevant for ancestry, in short they test less but a higher quality set. A good calculator doesn't need 1 Million SNPs, not even 100k, it needs the right ones and a good modeling of components / populations, which is way more important than testing hundred thousands of garbage SNPs.

23 raw data are often slightly more accurate, better genotype rate,.

I agree. Unless you have relationships at a top university genetics department that can test you, 23andMe is currently the best

23andme has the better admixture test for people of mostly European origins, and traces direct maternal and paternal lines.

AncestryDNA is much better for genealogy, and also has genetic communities, and better admixture results for non-Europeans.

that's my next big purchase

It's 2021 now, 6 years after this thread was created. I have both tests done, and while 23andme used to be better it got stuck years ago and stopped improving. AncestryDNA is far more superior nowadays. It broke down my ancestry impressively.

my new update:

they've given me Scottish ancestry ( I have no known ancestry from Scotland), and less Irish (I have loads of known Irish ancestry)
too much Welsh (I have a known great great grandmother from Bala in North Wales)

at least they've reduced the French ancestry (I have no French ancestry)

They seem to be confusing Scottish ancestry with Northern English and or Irish...and still confusing some French ancestry with Northern Spanish

The fact that you have an Irish GC and no Scottish GC would seem to imply that they are having problems with Irish and Scottish ancestry.

Yes I agree.
My maternal grandfather was pure Irish by blood.. His mother's family originated in Newry (hence the big match I have there) , and his father's family originated in SE Ireland
My maternal grandmother (whom I have v extensive ancestry records), was 1/4 irish, 1/4 Welsh, and 1/2 Northern English (originally from the NE not far at all from the borders)
I think Ancestry are confusing my grandmother's NE English ancestry with Scottish tbh

I've ordered and sent off an Ancestry kit, and I am excited to share my thoughts on here =) lets hope I learn enough new things from the results .

AncestryDNA is for geneology. So its actually useful.
