Regarding 666 Satan... I really liked it a lot (I was the mod of the 666 Satan section here after all). Compared to the slow pacing Naruto, 666 Satan was a fast paced rollercoaster in terms of story telling. Where Naruto needed a whole chapter to realize something, Jio would need a single page. As a main character, Jio was also just superb developed and had a cool power, especially after the timeskip <3
I've never read DB but both Kishimoto brothers don't make a secret out of the fact that they're DB fanboys and heavy influenced by it. The problem with 666 Satan is, that it could have been awesome when the mangaka wouldn't have fallen back to 'kiddie conclusions' all the time. It had drama and very interesting character and so much mature story potential but he destroyed it by putting too much effort in pleasing the 'young teenies' audience with stereotypes. To top it, the end was rushed and just very disappointing. Though, I still recommend it just because it has it's awesome epic parts and wonderful characters and artwork.
That mangaka has a habbit of not finishing his series, sadly. Which is a shame since Togari is really nice. Whether he'll pick it up again or not, we don't know. But the ending is left open enough to do so.
Though, this poll is two years old but Naruto isn't even in the
TOP 50 of Japan's Top Manga while FMA is #4 ^^;
You do know that there's currently a second FMA anime airing? Episode 4 will air tomorow, check out our
FMA section.
Also, the manga story differs from the first anime. It's much better in terms of plot and characters, so definitely read the manga and join us in the monthly discussions
