I’m in the city of Calpheon running through the quest that has you choose between two family’s but i don’t know which one is the better choice please advise lol

Why better? Better for what?

Each of these "decisions" opens a different path of history and generates different knowledge within the game to increase the "effort". In the long run it is convenient to make each of the story lines with the different alternate characters to obtain as much knowledge as possible. Regardless of the host line taken the rewards are the same, so it doesn't matter what decision you make, in the end you get to the same point on different paths.
