Attack on Titan - In my opinion, the manga is better.
Fullmetall Alchemist - Brotherhood or original?
Naruto - +1,000,000 - One of my all-time favourites.
The Seven Deadly Sins - Season 1 is the best, Season 2 was alright and the less said about the third season, the better...
Akame Ga Kill! - Both the anime and manga are good but the manga is far superior purely for plotline sake...
A very respectable opinion, friend.
