I have mostly collected the designer dolls, but I do have 2 of the LE dolls. Almost all of mine are the same characters- I have Cinderella, Belle, Jasmine, Mulan, and Rapunzel from the 2011 Designer set, none of the villains (didn't care for them), and then the 5 dolls from last year's release. Cinderella was always my favourite growing up, and I loved Belle (although I wasn't allowed to call her my favourite since she was my older sister's favourite lol) and I really really loved Jasmine when Aladdin came out. Recently Tangled came out and I loved Rapunzel so I wanted to get her dolls as well. I started following the Frozen hype mostly because I love snow (like, cannot stand spring and summer lol, I am happy to be waist deep in snow) and I heard Idina Menzel was going to be playing the snow queen. So when I saw the blog post about ordering the November Elsa doll, I went ahead and ordered her and my sisters gave her to me for Christmas. That was my first LE doll, then in January I ordered the Nordic Anna to match. I almost got the LE Cinderella when she came out, but I wasn't big on the design of the doll so I decided to just not get her. I am planning on getting the Cinderella from the upcoming set and possibly Aurora because I do like her character and would like to own a doll of her.
I agree, I am more partial to the designer dolls, they look so nice displayed and I love the merchandise that comes with them, but since getting LE Elsa and Anna, I can see the quality that goes into the LE dolls. They are absolutely gorgeous. I have to say I'm a little bit disappointed with the upcoming fairytale set, last year's set was very nicely detailed with the different fabrics and embroidery and lace trim, this year's seems a little more rushed and less creative. Cinderella looks amazing to me, and I like Aurora's face and hair, but I hate the bottom part of her dress so I'm iffy on it. I'm not collecting dolls after this though, I don't have enough room for them and I'm getting a little dolled out. I only collect the ones I really like, but even so, I have 10 designer cases and need to find a new bookshelf to display them, and 2 LEs that are displayed on a small end table in my room. I'm going to be moving within the next year and I shudder to think of moving them all, it'll be a nightmare, especially as I cut out all that plastic backing so I'll have to pack them really securely.
