The show is so great that you cant even put it into words... It is by far the greatest anime of all time... Were depressed for a week when the show ended....
It all depends on when this fight will take place. In the original series Rock Lee would win - No Doubt!... In Shippuden Naruto would win. Naruto just keep getting stronger and stronger... Rock Lee would put up a good fight though...
No fictional character stands a chance next to Goku... DBZ is way to much, if you ask me. The power level does'nt matter. 50.000 or 10 million. They can easily destroy a planet.... Superman is strong, but not that kick-ass :-D
