Xtion near shooting


I am a VVVV newbie and just venturing into the interactive projection arena.
Most of you are using the Kinect or the Xtion. I would like to know which is better if i’m gonna use it for motion capturing near the device.
I have found to that a little youtub video in that i seems the xtion can’t do good near capturig. But the video is alredy a year old and it might have gotten better.

I’d really appreciate all answers and sorry for the bad english.
