I was introduced to Naruto through the dub, so I originally liked it better. If it wasn't for my brother, who was a YouTube fanatic, I probably wouldn't have known about the Japanese Version [le gaspeth =o].
I prefer the Subbed version now, because, to me, the majority of the voices match up better. I like how they matched the VA's up with the ones in Japan so accurately at times. At one point, I could barely tell the difference.
But I still like some English phrases better [a.k.a. 'Pervy Sage']. I crack up everytime Naruto says it. :3
I keep up with the dub, but I skipped the whole Garra/Naruto fight and Oro/Saru fight. They drag on too long. .___.;
