The main divide here is worldview. Apologia teaches science from a Christian perspective, including creation-based biology and biblical references throughout. Real Science Odyssey is secular, teaching evolution and geological time without religious framing. Beyond worldview, Apologia is more textbook-based and reading-heavy.
Real Science Odyssey is more lab-based and hands-on. Apologia has a stronger reputation for college preparation in the upper levels. Real Science Odyssey is stronger at building experimental thinking skills in the elementary years. A number of families use RSO for elementary and transition to Apologia for middle and high school.
