Parents credit BFSU with teaching genuine scientific thinking through conversation and simple demonstrations, and they love that it is cheap and works for several ages at once. The main complaint is the preparation: it is not open-and-go, the plain text can ramble, and a parent has to digest each lesson before teaching it.
Families, especially secular ones, praise the real labs, the steady focus on the scientific method, and a friendly tone that works even for parents without a science background. The trade-off is heavy parent involvement: labs need planning, some supplies are hard to find, some are messy, and a few math tasks may stretch younger students.
Neither is better for every child. Building Foundations of Scientific Understanding (BFSU) is the stronger fit for living books (charlotte mason); video lessons a big plus; charlotte mason. R.E.A.L. Science Odyssey is the stronger fit for textbook + labs; independent workbooks; some.
