I feel like choosing bleach is bad because it has to little villains. you can easily make fillerd everywhere but in bleach there's very little room. it all happens in around 10 months max, not counting timeskip, in Naruto there's more than 2 years of content from Naruto's graduation to Naruto vs Sasukes final fight. not counting the timeskip which could easily add in a lot of things, unlike the bleach timeskip where it only has Ichigo just studying a lot.
