What are the key differences between mspy vs family link?

Hey, I’m not a parent, but I’ve been researching monitoring tools for, uh, personal reasons. From what I’ve seen, mSpy seems to offer more advanced features like social media monitoring and keylogging, but Google Family Link is more focused on screen time limits and app blocking, with a simpler setup process. Has anyone had any experience with the accuracy of mSpy’s GPS tracking, by the way?
