Is the 4gb Zune better than the Samsung T10 or vice versa?

I'm deciding between the Zune 4gb, which is the smaller ipod-nano sized Zune or the Samsung T10 player which has that arrow touchpad, and the cool "Sammy the Dog" animations and the really cute kid-friendly interface. I can't decide which one i want, So i would like to have some opinions from anybody who dosen't mind sharing their view points. I really appreciate anyone who answers this question! Thanx! =)
