Corolle chou chou twins?

[LittlePrince_Mom]

I know we've talked dolls a lot lately. I want to buy my b/g twins dolls for their upcoming 1st birthday. I narrowed it down to the Corolle Calin based on everything I've read on this site. But as I went into online stores to search for a deal I kept stumbling across the chou chou twins. As I need a boy and a girl doll for MY twins, they seem to make sense as a purchase, especially since I would be saving quite a lot. Are they different from Calin? How so? I know that they're 11" vs 12" Calin. As they are meant to be first dolls for 1 year olds, that might even be an advantage, no? I'm not in the U.S. so I can't check them out IRL. Can anyone who has these please enlighten me? I'm not one to buy lots and lots of dolls, I'd rather have 1 or 2 good ones. Should my 1 doll purchase be Chou chou?
I know I'm agonizing over this way more than necessary, but who other than you understand?
Thanks a bunch
