I like outranking. They focus on providing high-quality output for a first draft and what it would take to rank a particular article.
Something that separates Outranking this is that I can always count on the articles generated here to be great first draft Top Tier content. Additionally it will read your website's sitemap to find the best pages to link to and from to help distribute page authority.
The down side is that it's pricy, but you really do get the quality, and the team is always looking for ways to make the platform better.
