It depends on what you mean.
You can use BAS to automate, HARO for guest posts, GSA SER for contextuals, Ranker X for Web 2.0s, SEO Neo for PBNs, and last but not least, you can combine Zennoposter + BAS + Python to automate even money sites like PBNs.
It all depends on the definition.
For my niches, I never wanted guest posts and have used them no more than a few times. So when I say high quality for my niche, a good link from a Web 2.0 site, an article directory, or even a comment from a <30 OBL link is worth it and works. It all depends on the niche.
