What to do about my 3 almost 4 year old

Last year we tried to put her in a Catholic pre-K-3 program and it was a huge fail. She had a potty regression, went to the principal's office, just overall not great. But she seemed to be having a great time there. She kept saying throughout this year how she wanted to go back to "church school." Well she moved up a class at daycare and I think has made good friends in her class. She's always talking about her friends. We recently went back to the Catholic school for an assessment, and they told us she can start. When we told her this, she said she wants to stay at her daycare and doesn't want to go back to "church school." They cost about the same, so money isn't an issue. Her siblings will still go to daycare. I think she'd get more traditional education and schooling at the Catholic school, the daycare's pre-K program is a little chaotic. I really want her to be leaning. What would you do?
