I've read 1-10, and now im curious on everyone's opinions

I've read the first 2 arcs (i dont know what you guys call them but i mean the first 10 books) and a little bit of arc 3, and im curious what everyone else thinks of the series since I have no one else to talk to. What book is your favorite? What arc is your favorite? How would you rank the arcs? What do you think of arc 3's location deviation? Who's your favorite character? What is the coolest plot twist? I just want to know pretty much all of what everyone else thinks of the series, because I'm very curious (you dont have to answer the questions I asked here exactly). Thanks ❤️
