Query: Not as good as Naruto but great as a stand-alone!

Im sorry but ninjas are cooler then pirates. And arguably Naruto has a better leading character and better support characters. This is a close second but since Naruto is now getting its own show on Cartoon Network I feel it has a bit more of an edge. This is definatelly a great manga thought, dont be afraid to try it. Just do me a favor and try Naruto as well. =)
