I have shoes from all three. CL is questionable for comfort, and the D'orsay design may date them. But they are very pretty. I have a 5" pair of Choo's that is wonderful. The design here is very pointy and may date. But they are also very pretty. MB's are my favorite for comfort. Of your choices, the MB pair is most classic looking and is my favorite.
Now...to muddy your waters...I have a nude
Prada pump in an almost patent saffiano which is my go-to for a comfortable nude classic. It's shiny yet doesn't scream "patent". The toe is on the pointy side, but not like a needle point. I just love that shoe. Please update with your choice!
