Yura Yura by hearts grow is also really good, after almost more then 30 seasons most all of the op and end songs from the Naruto series are kinda great.

Guren no Yumiya from Attack on Titan is a great opening. it's one of my personal favorites. and Goya no Machiawase from Noragami and Kyouran Hey Kids! from Noragami Aragoto are also good.
