Naruto: Shippuuden Episode 3

[XanBcoo]

ok so here are the 3 technique
Chidori: require decent amount of chakra and fast moving speed(something naruto and sakura both lack) because unlike the Rasengan and Sakura Punch the Chidori is a piercing stab rather than a really powerful hit, it wouldn't be very effective if you can't execute it at an extremely high speed.
Rasengan: require a huge amount of chakra (sasuke and sakura doesn't have this) and very good chakra control in order to execute.
Sakura Punch: require perfect chakra control (sasuke and naruto can't control it that well) in order to focus chakra at the exact point in your fist.

each of them learn a technique that benefit from their strong point, saying one is useless would be pointless because not everyone has perfect chakra control, a large pool of chakra or fast moving speed.

Ok...but, the Chidori doesn't actually require speed in every situation. Sasuke used it on Naruto while he was standing still, and still managed to impale him. It's just as effective when used as a simple jab, or punch. Same as Rasengan or Sakura's attack. All three do the same thing.

2) Strength vs Rasengan....
Under normal circumstances, you should be able to defeat an enemy just as easily with a kunai as with any of the advanced assassination jutsus, however there are circumstances where sheer power is needed. When Tsunade fought Kabuto and Oro, would her punch have been able to inflict as much damage to Kabuto as Naruto's rasengan did? The rasengan does more than just break some bones, it's like a hollow-point shell, where upon impact it expands and inflicts massive area damage throughout the enemy's body.

I see what you're saying, but ideally shouldn't either attack be a lethal blow? I guess I'm working under the assumption that when any ninja has a good window for attack, it wouldn't really matter which attack was used, as long as it kills or incapacitates the enemy. In which case, Naruto's use of the Rasengan (in the fillers at least) seems pretty useless since he already has the chakra control needed to focus it all in his hands.
