I appreciate the work of all translators, but some of them just give me a headache. I would like to read stuff that I would also see in published work. Good grammar, punctuation, spelling etc... Thanks!
Legend of Sun Knight (fantasy) and Dominion’s End (post-apocalyptic) translated by Prince Revolution, are the best fan translations I have ever read! Plus the stories are amazing too; they’re quite popular on NU. Can also try Yu Brothers’ Case Book (supernatural/crime) if you’re alright with minor horror. But also...what have you been reading? Don’t most of the popular novels being translated have decent language?
Those two are great. Other than that, have you ever read from our trusted elder baka-tsuki? They translated novels before MTL become popular, and is pretty strict with grammar. I suggest Ghost Hunt, Utsuro no Hako to Zeroth no Maria (Hakomari), baccano!!!. Some might not be available in their site anymore, but as long as you look enough you will be able to find them.
