A: Hi Sumo-ling! Yes, there are some features that are unique for SEO SpyGlass. First and foremost, there's no limitation on the number of projects you can create and work on with SEO SpyGlass - analyze as many domains and build as many projects as you wish. Secondly, along with our own backlink index, SEO PowerSuite pulls links directly from Google Analytics and Google Search Console (an integration that no other backlink tool can boast of). Also, you can use the unique Penalty risk metric in SEO SpyGlass to identify the potentially harmful links and create a disavow file right in the app. Finally, since it's a desktop application, you can keep working with your data even when you're offline :) I guess I might have missed something, so if you have more questions, please don't hesitate to reach out!
