/Friends/Public or Catholic

I have a brighting 5 year old daughter. She attended a pre-k through k Montessori school. I loved it but the closest is 25 min. away in another state. Friends will carpool but I am nervous about responsibility. It also ends in 6 and then she would go?! The school said transfer is smooth due to the fact they instill confidence. Or should I go with a catholic school which is 1/3 the price and close to home with bus transportation. We also have a highly rated public school, but worried about discipline due to the growing class size in our growing community. I don't want my daughter yelled at by teachers which I never encountered in M and the children were very respectful and polite. I love the uniforms and catholic religion being taught to my daughter. Is catholic school too sheltering for a child? I feel they cannot compete with public, but I also like the small community feel. Need advice! All 3 are so different and again I love the M method of teaching the best.
