Manga: usually good plot at the start but the author like to rush things, which ruined the plot sometime and I hate it. Manga are usually one-short with smut but some can be long.
Manhwa: color. usually very good plot and the drama with handsome boys. have a lot of smut(good smut btw). The plot is usually long and dont rush. (Manga should take note from them)
Manhua: short, short and fucking short. Color with 5-8 page, and if the author is nice she will give u 10 pages so far i have read. Sometimes they take years to update.
I personally like manhwa plot the most. Manhua is not much yet but yaoi manga was my very first bl. I have just been reading yaoi manga before manhua/manhwa come up. But i like all, as long as it yaoi i read it all.
Mine is: 1. KAITO from Radical Blood Monster. He is hot, handsome and caring towards his uke. Tbh I like all seme in Mishima kazuhiko-sensei work. 2. Chun Sam. He is adorable, sweet and handsome. 3. Endo. he is hot!! End of story. 4. Yuri from Never understand and Eric. 5. Victor from you know who where. He is not technical from yaoi world but you understand anyway.
