Similar Shangri-La Frontier

i recently watched Shangri-La Frontier. i was avoiding for few years even when multiple recommendation was there on you by watch mojo and etc. so i tried watching it and i am hooked just like one piece it made spot on my top anime list i have watched many anime by now but this was different i like good animation and well written story.

so my question is can anyone suggest the similar level of anime? (don't suggest AOT or demon slayer or JJK already watched)
