Call me biased but I do think Nijisanji's cover of Hikaru Nara was much better than this. Like someone else said, maybe it's because of the mixing or because of how they're directed but most of Council sounds off singing it compared to Inui, Hoshikawa, Akina, Yumeoi and Morinaka do.
I think that, aside from having a powerhouse like Inui, part of it is because the parts that are meant for male vocals are sung by the males and that the hook or chorus is supposed to have this harmony of female and male voices so Council's cover, especially if you're familiar with the song sounds even more off.
