What game is better for a nine yr old boy play station3 or xbox?

Sure he should and the only problem is that you waited too long and he will be so far behind his friends in his capabilities. The problem is some people value the past and history too much to understand what is important in a child's development is a rounded broad background. If something is left out it's much better that it wasn't something the majority of the children in the USA today spend their time doing. He or she should have already had a portable device for years and should have parents that can teach him how to use it not feel it is unimportant for them to have been able to teach. Yes he should have had a PS3 and a PS Vita for when playing away from home. Xbox 360 does not offer the family entertainment center a PS3 does and has no portable devices to work with it. Today it (doing things online) is how kids socialize with their friends whether it a a form of online playing games or other events these devices are essential for a child to have a normal 21st century childhood. The games do not have to be violent and many require intelligence for planning not just a manual capability of using the controls to shoot things

No. Many of the a games are too violent and he needs to go outside and play Baseball or to socialize with family and friends.

Playstation Home has a virtual world where individuals create and dress characters and learn to practice doing adult things from decorating personal spaces and earning rewards, it the dress up dolls and dollhouses of the 21st century for my nieces and nephews. There are so many different items available because of the virtual world they can have an almost unlimited number of choices
