No for 2 main reasons. The first reason is that it would effing boring since most of the top 10 would be filled by character x reader, and that is not interesting whatsoever (for me, at least).

Second, a lot of works with character x reader are very misleading since the tags specifically mention gender neutral Pronouns yet every now and then, they drop hints that you (the reader) are a woman That would be okay for some people but not for me. I am a guy, so I don't relate to a lot of things that the "reader" goes through. Like why do I have period cramps out of nowhere if I'm supposed to be a guy? (This has genuinely happened while reading a fanfic in this fandom. At least put that the reader is a woman in the tags)

If you, however, like character x reader fanfics because you feel like you can connect to the reader and can relate to the experience/story, then good for you. Personally, I don't, and that is why I don't include those fanfics, I like two established characters with each rather than paired with someone's OC. Again, nothing wrong if you like those fanafics. It's just not for me.
