I don't practise either religion, but these are pretty much my only options within a two-mile radius.
There are many ”outstanding” Catholic schools, but I've heard that the Church of England takes a more lax approach to religion than the RC church, where converting to their religion is the top priority.
Note: I don't need to be told to find a school that is not religious because I don't want to have to take my son on two buses in the morning and two in the afternoon.
