I just learned today that people actually look at ratings. I honestly never trusted those ratings because of myself. When I rate a Manga/manhwa it's when I want to subscribe to them and keep them (if I don't rate, the site unsubscribes for me). So since it's almost allways uncompleted works, I put 5 stars by default
I rarely read anything below 9.0. It depends on your taste but most yaoi (bl) under this rating often have r@pe or not clear consent sexual activities. Sometimes its the art or if the story doesn't have a clear plotline. If the story is 8.9 then it just means that people have been rating the story with 4 stars.
I just did a quick glance of your reading list so I just chose what I think you might read (as I said, there's plenty of good ones):
