My parents are catholic and anglican. We attended a anglican church when I was a child....until the church changed priests and my parents thought the new priest was a hypocryt and we stopped going to church completely as the next closest church was too far away to drive to. My Dad to this day still calls himself a "non-practising catholic"...he never referred to himself a anglican.

As a adult, my first serious boyfriend was catholic and I attended church with him on several occasions....and to be prefectly honest (hopefully without being offensive), the only difference I could see to the church I grew up in was references to Mary where Jesus or God/Lord was referred to in the anglican church. The prayers and even the structure of the service was almost identical.

If I were at this time, a practicing church goer and I had the choice of a catholic or anglican primary/high school to send my child too, I would most likely choose anglican as this is the church I attended as a child, but I honestly believe the differences between these two churchs are so minute that it should be considered "wrong" to send your child to the other church's school. If you were talking catholic Vs Buddist....that might be a different story as the religions are very different and have very different beliefs.
