are you talking about the ui and textboxes translations or about sex scene voice translations?
Honey select unlimited doesn't have sex scene voice translations at all and i think most of the sex scene voice translations in the fan mod are somewhat google translated.
For the other ui and textbox translations: i'm no natice spealer but there both versions made sense for me. (but i encountered an untranslated archivement and some typos in honey select unlimited, but on the other hand un hsu the english text is not weirdly placed above the jp text like with the fan translation)
To conclude, both versions are broken, just different (like with hsu and hs different sex positions are broken, hsu way less positions with telescope dong, but broken g-spot position and missplaced dong in sitting reverse grinding position)
