I love ahrefs. Huge fan and power user.
With that being said, there is one area of the platform that I feel has yet to catch up to SemRush and that is the competing domains report in the organic section.
This report feels very sparse with limited features. With competitive intelligence being such an important elements of SEO process now a days... it would be great if this report could be greatly expanded so that we could export a large set of data to work with... similar to how SEMRush does it (and hopefully with additional features to deep dive & segment on). Right now I am forced to pull organic keywords via ahrefs ... but go and pull competitors from SEMrush... and then come back to ahrefs. Would much prefer to stick with ahrefs to steamline our processes for enterprise clients.
As a starting point, being able to see and export a much larger list of competitors would be appreciated.
