Niche edit links and PBNs

Hi all, I'm trying to find more information about niche edits links. Is niche edit links more powerful than PBNs? Or it does not necessary have to be that way? And how do we determine if the niche edit links are powerful? Based on the RDs?

what is niche edit links? guest posts?!

in niche edits you won't have to spend money on tiering links.
