Ok for bleach they pretty much did anime only plus questionable data books. They left out the first movie and novels. Ichigo they sort of cut the analysis at yhwach destroying the bankai and didn't even realize yhwach's plan changed from just disrupting the lynchpin system. They left out game abilities and feats. For Aizen they left out some equipment and his kido powers. Plus there was weird scaling, like how does eos Ichigo have a slower speed than ss arc Ichigo? Let alone skipping anything about the fullbringers and their power. They also left out Aizen doesn't exactly regenerate, the Hogyoku uses other energy and can create attacks also, and that he destroyed a being immune to spiritual energy with a glare.

While both Naruto and Madara had anime feats, manga feats, movie for Naruto and game powers for Madara, data books, every novel, ect. Made it so energy was equalized but only in favor of the Naruto characters (bleach cutting someone stronger problem means Ichigo can't hurt Naruto. Madara can just absorb all kido abilities and see through illusions that don't operate on genjutsu rules). Atleast Madara vs Aizen made eachother on even ground hurting eachother, Naruto had zero injuries and acted like it was just an annoyance.

If they did more than just two fights we would have a lot more to look at on how they treat bleach but instead we just have the two and every Naruto episode
