I am looking at Ahrefs DR and UR - UR is most important factor - it reflects backlinks of that page.
Majestic TF sometimes is usual for PBN setup to check strongest version of domain / URL.
But the same can be done with Ahrefs - and even better and easier to find strongest URLs of domain.
Ahrefs is most powerful tool for backlinks - they see all backlinks, if it is not hidden from Ahrefs crawler.
Metric are nothing - it can be made by spam links, GSA blasts, etc.
So it is needed to check actual backlink profile manually.
Also, many link sellers are getting their link prices by their websites traffic volumes.
