I see the difference in leather and color of HW of old and new boy on the side by side strap comparison. I don’t see that much difference between the clasp and two strap nobs, but it may be the lighting. I used to have the boy from this collection as your older one. I liked the more matte look and softer feel of that caviar. I can’t really speak for the new boys as I have not bought a boy bag for a while and don’t know what the new caviar on boy bags is like now. But from the picture of strap comparison I like the older caviar better. It looks like better leather quality in my opinion, but again I have not handled the newer boy bags. I also see Chanel added the little loop to the strap at the end. They did not have that before from what I remember. They only had one loop before the nobs. Now the strap has two loops?
