I think Mikey is better for an older boy, the Millenium boys seem to remain babyish in their features no matter what you do...so I think if you want to depict a child from toddler to say 10 use millenium boys, after that use Mikey...Mikey has more of the transitional features and really seems to capture the gangliness of a teenager... I don't think he looks like a hoodlum, but there is a certain amount of rebellious youth captured in this character...:-)
