Loyola you say has much better academics, plays in a better league and both HS produce great players so for my son I would push for Loyola. Sure a few more players at La Mirada go D1 but if you are D1 material you will be found at Loyola, according to you, and if for any reason you won't be playing college baseball (injury perhaps) you have better academics to get you into the school of your choice. To me, your question sounds like an endorsement for Loyola. This would be an easy decision in our house but please note I don't know either school and I am basing my answer on your descriptions.
