Chanel 21S Iridescent Pink shiny puffy calfskin or 21S Light Pink Caviar?

I am struggling to decide between these two stunning bags from the new 21S collection. I personally always love quilted lambskin for its luxurious look. I also heard about how durable caviar bag is especially for light color bags. While the iridescent color gives the unicorn looks to the pink, I want to know how the iridescent color work out and how easy it would be maintained. Thank you 😊
