I would have to say w.i.t.c.h, they are much easier to interact with,and are favoured سے طرف کی the animators, plus آپ can relate to them مزید 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.
I like both of them.I like W.I.T.C.H cause of they're great firendship and know how to work together and I like C.H.Y.K.N cause the have mad skills and awesome outfits.
