DA vs DR

[Bratter]

Hello everyone! I think that I am the first who ask something like that. Can someone describe to me the difference between DA from MOZ and DR from ahrefs? Cause I want to purchase some backlinks to my website. And different services use these two metrics. I dont know what the most quality is.
Maybe you will share your own experience with these services.

Moz and Ahref have set up their SEO metrics. Moz call it "Domain Authority" whereas Ahref call it as "Domain Rating" which shows strength of a given website’s overall backlink profile. Both the tools rate Damain on the scale between 1 to 100, 100 is considered the best. DA above 40 and Dr above 70 is considered a good score. Try to get backlinks from sites that have DA/DR above mentioned numbers.
