Just to remind you, Ip Man and everyone in his verse is bordering to 9-B due to
his calculation reaching 14 kilojoules. Ayanokouji doesn't seem to have a calculation so his strength is probably baseline which is 300 joules
That means Ip Man is 50x stronger than him. This is a one-shot. However there is still hope as Ayanokouji has fear manip from looking at his eyes
Give them both prior knowledge. Ip Man can just focus on getting a body shot while Ayano just has to force his enemy to focus on his eyes.
In which case, I think I'll vote inconclusive as they both can kill each other really quick. This is only applicable if prior knowledge is given though
