I would have to say w.i.t.c.h, they are much easier to interact with,and are favoured by the animators, plus you can relate to them more because they're kids with the same promblems as some children today example: Will's mum is divorced, Taranee having a over protective mum, in the comic Haylin's grandmother dying etc. The last generation of guardians however, don't have enough screen time to get use too, thus unrelatible, but it's just my oppinion.

w.i.t.c.h is way better

I like C.H.Y.K.N better.

WITCH!!!!
