eternal question - lambskin or caviar

I have the jumbo black with lambskin and I use it all the time, and I am very hard on my bags. It has no damage and is holding up very well. I love the silver hardware, but that is a personal choice.
 
I have this bag in the Caviar and love it. I think it may hold up better if you would be using it more often.

If you're only using it here and there, I would go for the lambskin.
