Ancestry/Genealogy

MyHeritage had a lousy DNA site when they first got into the business, but they have improved things greatly. Still, they say that I am 51% Iberian (Spain and Portugal) and all of my research has shown that I'm 100% French-Canadian.

23andMe is still my favorite DNA site, they do some haplogroup testing, and the fact that the uncle of my first cousin once removed match shares a maternal haplogroup with me means that they are on my maternal side. The uncle also shares some X chromosome DNA with me that indicates the same thing. 23andMe has an ancestry-only product that they sell in the US, and it is half the cost of the ancestry-and-health product that they push in advertising.

If your newly discovered relative has not tested on all of the DNA sites, I'd advise her to do so. You have to fish in all of the ponds.

As for the records from Ancestry and MyHeritage, I use both in building pedigree trees for my matches. MH is integrated with RootsMagic software, and as I enter information on a matching person, it suggests names and data of that person's parents, etc. But, it is not perfect, and I use them both together to find trees for my matches.
