Metrics to look at before getting a link from - DA or PA or Spam Score?

[BiggyIdeas]

If you had to get a link from a site then how would you judge the site? Would you judge it by it's Majestic metrics such as TF/CF or Moz metrics such as DA/PA or as some like to say check 'spam score'?

I know it be a odd question to many here. But I am just confused here. Everybody suggests to get a link from a good site. But nobody says how to decide the site is good or not.
