Your choice between Ancestry vs 23andMe will depend on what you want from your DNA testing kit. While they both provide similar results when it comes to finding your genetic makeup, ancestral roots, and building your family tree, AncestryDNA has a larger database and more active users, making it the best DNA test for finding relatives.  The service also has a better range of resources, such as military records and newspaper archives to add context to your results. However, 23andMe provides a lot of extra health results, allowing you to check for genetic diseases and other predispositions. So, if you’re looking for the best DNA test kit for ancestry, go with AncestryDNA, but 23andMe provides the best human DNA tests for health.
