Tailed beast bomb is a technique and transforming into the fox fully is a bond. One does not make the other. Also I think naruto would win to. His speed and power with it would be quite a show. But right now we know to little information about naruto's cloak's form to make a exact answer. Fully controlled nine tails naruto will win for sure but who knows when that will happen if it does.
Also this is the wrong forum section just to tell you. You may be new but still it's best to read where to put stuff. :\
