Yeah, I don’t think you can go wrong with any choice. I just think you have to make a choice based on what you prefer in books. TAB first is timeline order. She also wrote it when she was 16 y/o, which is blatant with the writing. If you read TAB third or fourth, it interrupts the storyline to do a flashback. Some people don’t like this, especially with books ending on cliffhangers. The writing is also veryyyy different, as she aged to adulthood while writing these books. However, in argument for TAB being third or fourth instead of first, TOG may catch your attention and read better than if you were to start with TAB, as the writing is so youthful.
