Whatever elementary school your child is going to and they are happy in is the best.
In over 20 yrs in real estate I have never had anyone from any school want to go to a different school district because they felt the school was inferior. Every teacher is different and some schools offer special programs. Administrators in the school may make the school climate better or worse for teachers or students, but those things change and rather frequently. Best thing to do is make an appointment, visit the school and meet the principal and some staff and compare.
