I'm just going to mention the ones I can remember a general idea of all their chnhn fics and if they got more than 3 chnhn fics (there's a lot of good writers with one to two spectacular chnhn fics in the tags though!)

SAGE AKA CHOCOLATEMILK139 especially I think for emotional in depth, tear jerking, chnhn or like tension filled because they're idiots in love but won't admit to being in love until the other gives way or they finally get out of their head.

chanhoonist is good at more tsundere and stubborn jhoon and very stubborn but soft hearted fool chn. they're at conflict with each other and their own feelings yet they have an undeniable pull to each other type of vibe

zhask is similar as well in that but their fics are usually in the more G rated compared to chanhoonist!

zvirk77 either hurts you with the freaking angst or drown you in the horny chnhn. there's no inbetween.
