[Obligatory rant about how the proprietary metrics that Moz and Majestic provide don't directly influence rankings goes here]
But if you want a straight answer:
- Moz metrics are useless garbage, so there's no straight answer to give for that one
- Backlinks from pages (not domains, pages) with a TF of 30+ can generally be considered quite strong. Generally.
Edit: I changed that TF value several times, by the way. Originally 20 then 10 now 30. That should give some context as to how difficult/pointless it is to give any kind of straight answer to this question.
