Why was this ever a debate? I swear most non canon ships have better dynamics and relationships than anything the canon can ever devise. This is especially true in pjo fandom. Not a single good canon ship in the entirety of the ten book series and then all the other sequels/spinoff. And I mean not a single one. Percabeth and solangelo speak for themselves. Jiper and Caleo couldn't be more disastrous. Frazel isn't well fleshed out, and so on. No one's saying they couldn't have been good, but it's the truth that they aren't. Rick's writing plus certain tropes have ruined them completely.
Another point is that they are all teenagers with heavy trauma. They could have been fine without relationships. Rick could have focused more on their individual arcs and them overcoming their own traumas. There was no need for any ships. Rick acts as if a relationship is the solution to all the character's trauma and ptsd and the fandom is going along with this? Come on.
