I'm not as hyped about these two characters as some people, but I do like them somewhat, so I know I'd get at least one of them. Probably Cloudchaser for her rockin' hair. Honestly, their color palette is so similar I'm not sure I'd spring for both of them, although I'd most likely be tempted. While pegasi are my favorite of the species, in this case the fact that they both are actually works against their favor for me, as it doesn't help differentiate them at all.
So I'd get them, or at least one of them, but personally I'd prefer some other pegasi, like Thunderlane or Blossomforth (or Daring Do, for that matter) be made first. They had more of an impact on me, but that's just the way my own "wants" rank.
I was going to write my own brushable vs. molded reasoning, but I've been sick today and I'm so tired now I'm not sure I could get through it or that it would even make sense. Maybe tomorrow, if I remember. *yawns*
