It's a different kind of picture quality, so I would not call one better than the other. If you enable Scanlines on 480i input on the XRGB2+ you get a picture which essentially looks like the interlaced picture on a tube. In terms of pure deinterlacing the XRGB2+ cuts the vertical resolution into half (480->240 lines). The HDBoxPro keeps the resolution and only reduces it in portions of the picture where neccessary.The image quality is FAR superior with 480i & 480p games like Gradius V & God of War, respectively. XRGB-2+ does an adequate job with these games, but the HD Box Pro just seems to give a better quality image.
The new DVD Edge got a new 240p processing mode last week which makes it - scanline emulation aside - the very best videogame processing device out there. At $700 still a bit more pricey than the HDBoxPro though
