Apple's is by far the worst. All feedback is private. There is no way to show or advertise support for feature. Like I want to go upvote the feedback from this video, but all I can do is file my own feedback, which is more work, and therefore more people will choose not to give any.
Both Apple and Google and Microsoft have "users help users". These are infuriating as there is no official answer or help. There's just some fan with an often completely wrong or irrelevant answer. There is zero indication that any of these companies look here to see what's broken.
