Bleach is superior, but it lost its flavor. Also giant mechas with drills that pierce the heavens over both of them together. And that had 26 episodes.
Idk, I liked Naruto before it came to the states but I never got into Bleach, it just didn't interest me.
So for the sake of going with what I know I have to say
Fruits Basket.
Easy, Z warriors> Soul Reapers and Ninjas combined 
.
We talking series as a whole? Early Bleach was fantastic, late Bleach was horrible. Early Naruto sucked so bad it was scary. Later Naruto is brilliant (till you get to the recent stuff which goes the 
am i watching route). I would have to go quantity Naruto cause there is more episodes of that that i enjoy mostly Shippuden, but Bleach at least when it was good stayed good unlike Naruto that went good and then went bad again.
I'd rather watch Bleach. Both do have some nice fights when they aren't talking half the time. Both are starter anime though.
