Angel Beats!, Durarara!! Recommendations
Both Angel Beats! and Durarara!! are amazing for the same reasons, including engrossing (but much different) story lines, lovable characters, great use of animation and art style, in depth development of characters and much more. For this they're both similar and just as amazing as each other. Don't let the difference in genre put you off, if you enjoyed Angel Beats! and can handle violence in anime then I 100% recommend Durarara!!
