Irrelevant factors.
If they are getting the same thing when it comes to what the entity giving it is supposed to be doing, those other factors don't matter.
Really ? Ok let's throw an example out . Public schools . Do you think all public schools

Schools are like neighborhoods. When you talk about a neighborhood, you can talk about the churches, the schools, the shopping malls, the entertainment, the property and home sizes. But what really makes a good neighborhood are the neighbors. Same holds true with schools.
I was taught in a Catholic school and a very small one at that. We averaged about 40 kids to a classroom. We had no lockers. We had no cafeteria. We had no library. We had no football fields. We didn't switch classes. We didn't have college educated teachers; we had nuns. The class that they gave you was where you sat all day.
Yet student per student, we would out perform any public school children on any level of academics.
