Personally, I love the chroma-key wall because you are able to have the true resolution of the graphic appear on the screen to give the viewer exactly what you mean to present versus the wall that is projected, lit, faded and poorly translated for television. The only drawback with chroma-key is the potential for key "noise" around the subject i.e. around their IFB or between strands of hair. It's definitely something I can get over in exchange for the full HD resolution graphics!
