That move you showed right here was Tiger Hunt though, not Oni Giri, which no-flame King no sold despite being hit in the head. Which means, according to your very logic, Asura > Sanzen > Tiger Hunt > Oni Giri, giving the order Zoro attacked in, scaling his attacks up vs. Mihawk. Especially since he used Tiger Hunt against Mihawk while having a Luffy flashback to show his ambition.
You did well playing yourself, Sanjikun-san.
