Having never seen any Naruto, I will now mentally substitute every instance of the name with Dragonball Z. I'm told the difference is largely superficial, especially for the purposes of this discussion.
Heh, whoever told you this is wrong. While there are certainly a number of similarities between the two (which are probably deliberate, considering that Masashi Kishimoto claims he has been greatly inspired by the works of Akira Toriyama, among other people), there are a number of major differences. The fact that Naruto is far more focused on character growth, psychology, and relationships than Dragonball by a significant degree, and that the battles in Naruto are rooted in ideological conflict and personal motivation, rather than the strict good vs. evil of Dragonball. As others have said, the characters in Naruto all have unique abilities and styles, and use them in very tactical battles. Dragonball characters tend to all use punches, flight, and energy blasts, and battles are pretty much slug-fests.
Also, the power scale in Naruto doesnt even resemble Dragonball. Dragonball has an exponentially diverging power scale, based on uniquely powerful characters gaining so much strength through obscure, insane training methods and unlimited super-transformations that no one can match them. As Dragonball progresses, fewer and fewer characters can even keep up with the rising power, mostly leaving Goku and Vegeta as the only real combatants. Being able to shrug off bullets and level cities is considered the power level of the average grunt soldier, and main characters can blow up planets.
Naruto, on the other hand, has a very shallow power curve which flattens out quickly, and most power increases occur because of learning new techniques and methods of attack. Every character is mortal and subject to being killed by a single stab or solid blow, and any increase beyond a certain level of power comes at incredible cost and risk. Pretty much all of the characters are soldiers of equivalent power who work in an organization, and the main character is grunt who is much weaker than the elite ninja, and aspires to become recognized (as opposed to Goku from Dragonball, who is just strong, and everyone aspires to be him).
Also, the characters in Naruto all come from a wel-established community, and they all have family and traditions which highly influences the plot and the character's abiities (and is a major theme of the manga). In Dragonball, there are only one or two characters who really have a family at the start, and only one or two families which really matter once the story starts crossing genreations.
I could probably keep listing differences for a while, really.
Certainly, Naruto and Dragonball have similrities, but the similarities are the superficial elements, and the differences are fundamental.
