I'm an Xbox guy myself, I would make a point for both systems, with respect to the Playstation line of consoles. But first to answer your question about the Xbox account, because xbox if a Microsoft product all you need is a Microsoft account. For the 360 I have to renew my online account every year other then that the account is simple to set up.
Xbox 360
Already have a vast variety of games
Bugs are rarely mentioned anymore
You don't need kentex to use the system
Xbox One
Newer games will eventually only come out for Xbox One
The system come with the kentex because the System updates itself daily, and when updating itself it also turns the kentex (camera) on
It's the first model of the console, so I'm sure there will be tones of bugs. once again its a Microsoft product
I would personally suggest getting the new Xbox One, or as CH312 said the PS4, so those are the systems you should be comparing.
