What a kind and generous thought!
I know unwrapping something is a thrill, but I wonder whether letting HER choose might be a better longterm bet (you could wrap up a big box, and put a note or homemade voucher inside it with some photographs).
It's a very individual thing and I'm 20 years older than your cousin but I can tell you my own experiences with both these exact bags.
My Chocolate Bays has been with me for 5 years and is still going strong. She is quite plain looking and quite heavy, can only be carried on the shoulder in light summer clothes but has the classic Bays shape which many people associate with Mulberry and is very strong. I love Bays so much, despite the limitations of the shape, that I now have several in different colours/leathers.
My Oxblood Daria Satchel was light and comfortable to wear, was a lovely colour and handy as a hands-free messenger. I really liked the big tree medallion, though I did wonder whether it would eventually look a bit "last year". But after one wearing, she had to go back to Mulberry and I do not plan to buy another Daria. In particular, the striking large shiny coaster appears very vulnerable to scratches and as it's such a feature, these will be noticeable. I can't comment on how strong she was, because I didn't own her for long enough but the leather felt a lot thinner than the classic Bays leather (mine is Darwin, newer Bays are NVT but both are strong) and a heavy load on the straps might possibly cause issues.
HTH!
