I can't comment on the schools, but when I was in high school back in the Stone Age, I remember one of my classmates chose Good Samaritan over Christ because she liked Good Sam's nursing cap more than Christ Hospital's! Honestly, I didn't even know what the caps looked like and I chose Christ Hospital. Back then, I think Christ Hospital School of Nursing had the reputation of being tougher because it was a two year program. (And they weren't wrong about that!)
Good luck to you whatever your decision!
