5pin. Gives the same amount of tiles to tenpai as the 9man. The difference is that 9man gives ittsuu, while 5pin gives a 58p wait on 6pin draw - but the 14s does that well enough already. It's a good idea to prioritise on the big yaku at this point.

It'll bring the hand to 1-shanten for pinfu, while retaining possibility for Ittsu. However, if a 3-pin ever gets drawn, gotta kick oneself on the foot.
