UT Dallas(public) or Baylor(private)?

Hi, trying to decide between UT Dallas and Baylor for business/engineering degrees(or Texas A&M which I'm praying to get into). They both seem about the same academically... I like the Baylor environment more.. But UT Dallas is public which means it will cost my parents a lot less. Could anyone please tell me some more specific reasons I should consider? Thanks so much !! = )
