I think Typhoon will win. It would be imposssible for Bigger Brother to approach Typhoon, get underneath and flip him over, when all the while he is spinning at full throttle, without getting damaged in the process.

And DONT bring Raging Reality into the subject; they only flipped Typhoon cos Kan Opener stopped the spinning.

Please, however, I know no spoilers. Even if I did, I wouldnt reveal them on purpose.
