I'm not sure. DotD is more flashy and has really vibrant colors, then GB shows the characters more relaxed outside of school. I love them both, but I'm slightly pulling towards GB more even if it doesn't include Ghoulia, Deuce, or Lagoona.
I wish the Dawn of the Dance line had a couple more characters but it is by far my fav. Much more original than yet another doll beach theme. Gloom Beach reminds me way too much of Barbie. But of course the creators, Mattel, also are the creators of
Barbie and I expected a beach theme
because of this. But I like them ok simply because they are Monster Dolls and I like Clawdeens hands in the Beach theme. I would rather have had a winter theme tho or a holiday exclusive (which I'm surprised there isn't one...there's always Holiday Barbie...how cute would a really detailed holiday outfit be???!!!) I'm sure there will be many more great themes. Monster High will be here with us more than a minute!
