[QUOTE=AssertnFailure]1) Gaara aka "one tail" and Naruto aka "nine tails"....
It's pretty much unanymous that kyubi would be stronger than shukaku, but yes Gaara is probably much stronger than Naruto. I don't think this necessarily has anything to do with training (because well, who could train Gaara to control his sand?). This has to do with the type of seals they have for their demons. Gaara's seal grants his demon greater access to him, thus allowing for the passive defense and instinctive sand control. Naruto's demon has like, practically no access to Naruto except in times of vulnerability, whether it be extreme emotion or serious injury.

If this is the case and the tails represent the strength, then how do they choose who gets what? Does the leader get the nine tails and it go down in rank from there? Or did they pull names from a hat? -dg-
