There are a lot of high-quality KBLs. Art Girl and others have already listed some of my faves. In terms of my own emotional investment (which is one measure but not the only measure of what's my "favourite"), two that come to my mind are "Eighth Sense" and the recent "Secret Relationships", but you've already seen both of these.
On this subject: Because Thai BLs generally feature established BL actors in whom I'm already emotionally invested before the series even begins, KBLs (and JBLs) are at a relative disadvantage, but they tend to make up for it in other ways (KBLs: consistently high quality and execution, JBLs: originality and creativity).
As to KBLs which you've not yet watched, let me suggest one more: "Wish You: Your Melody From My Heart", which I think is a nice, easy, engaging watch with good music. While it's not among the top tier of KBLs, I think it's very underrated (avg. MDL 7.4).
I had no idea there was a series! I watched the movie Wish You: Your Melody From My Heart on Netflix a while ago. I truly loved it. It has such an incredible storyline, with heartwarming and cute moments. The two main characters were so well portrayed and their performance was outstanding.
