I prefer the HD Projector, but ive only played games on it im not sure if thats what your going to do
3DTV is not that special, especially since there's not much 3D channels and decent glasses cost about £100. I get headaches after a while of wearing the glasses, might just be me but i cant watch it for long, and when you get up to get a snack or something its annoying with the glasses (unless you get high tech ones which turn off automatically when you dont face the TV)
