For me, my Wii looks very good on my 40" Samsung HDTV with the official Nintendo component cables, much better than through the Wii U via HDMI, but if you don't have a Wii, I'd suggest Wii U component (don't use Wii U composite, it looks dreadful, even through an SDTV) through an SDTV. Overall though, the Wii either looks too blurry or to sharp for my tastes, it's sort of like the N64. It's hard to get to look good on any setup.
