OP here- thanks!

Xbox One is the newer model. About 2 years old at this point. You don't want to buy an Xbox (even if you can find one) as there really aren't any new games being made for it.

Can someone please explain the difference between the two and which is "better" and why? I am totally confused. DS is 10 and has been asking for one and just told us he wants to forgo a birthday party this year and get a "big" gift instead so we are thinking about this.
