This is indeed a very biased comparision where some features in the comparision table are just claimed to be not supported by other (open source) solutions. Even after reaching out multiple times the article is not updated accordingly. So this has to be considered a sneaky marketing page to be honest.

I might be biased as I'm one of the Kowl authors but I can definetely tell that Lenses is affected negatively the most. Imo it is one of the most complete paid solutions and got the worst marks basically.

This is mentioned in my medium profile. If you think that my comparison is not objective feel free to mention it on comment there)
