Iโve attempted Fate/Stay Night & Fate/Hollow Ataraxia, and am currently playing through ใใใใใใใฎ: prelude to darkness (though I am not very far in). This is a stab in the dark, but Iโd put the Fate ones in mid to upper 30s, and ใใใใใใใฎ in the mid 20s. ใใใใใใใฎ has a lot of voiced lines. Fate has some, but also lots of inner monologue.
By way of comparison, I have an easier time reading Sword Art Online light novels than Fate VNs - both for vocab and grammar. Otoh ใใใใใใใฎ is definitely simpler than SAO - though some of the kanji are less common. I havenโt read enough other LNs to place it super well, but I feel more comfortable reading it without English than many manga Iโve tried.
For w/e itโs worth, jpdb has Fate at 7/10 and ใใใใใใใฎ at 5/10.
