What an odd comparison. Both are great games, but there's a MASSIVE difference in scale here. Child of Light can be completed 100%, started in New Game +, and completed 100% again in about 10-15 hours, without a walkthrough. DLC would stretch it to 20, maybe. Probably not. To complete Final Fantasy X alone 100% would probably take 60-80 hours, double that when X-2 is included.
Asking whether to get FFX/X-2 HD or Child of Light is like asking whether to get Super Mario Galaxy or Cloudberry Kingdom. If you like RPGs, you'll want to get both, but which you get first will depend on how much time and money you feel like investing in your next game.
