Which one is better?

The Xbox console combines powerful hardware, software and services to give you the most dramatic and lifelike gaming experience. The console is created to trigger your imagination and send you on a boundless journey.
Each system has a different set of priorities and you need to know it before you make your choice.

The Xbox 360 fuses together all available technology for your pleasure. Entertainment delivered straight out of the box with all the additives you can possibly think you will need. This system however is more suitable for veteran gamers, who can make good use of all this console has to offer and will not get confused by this plentiful offer.
Best gaming experience out there today that your money can buy.
The system contains: console, hard drive, wireless controller, live Xbox headset, component HD AV cable, Ethernet cable.

The Xbox core console is like its name, the core of the Xbox, so it delivers the same gaming experience as does the 360 but it starts you at the basic and allows you to widen your gaming experience with time and at your leisure. The system provides you with the basic tools you need to get started and then you can add more to it as you grow experienced. Adding a hard drive and memory unit in time will eventually enable you to the the entire Xbox350 offer.
