I think that strengt isnt depending on tails, i mean it does but not completly, its about how they fight, and also i agree on that Kyuubi is the strongest
Dude i am not saying he will win , i am saying he can win. My point was kurama has more chakra than him but that alone doesn''t put him above shukaku just like any other shinobi fight.
none of the bijuu has a chance against the kyuubi that was already established when just half of the kyuubi stomped 6 bijuu. Like I said having a sealing ability means the shukaku just has it, it in no way gives him the ability to win especially against something greater than itself. It does create and opportunity to win against equal or lesser things. A fight between shukaku and the kyuubi would last absolutely less than 10 seconds with the 1 tailed dead being reincarnated someone else. The shukaku has only a chance to win against the turtle bijuu, the rest are much better and can fly, shoot bubbles(range), are faster.
