Something like a Pioneer Kuro would do me nicely. No gimmicks, just top-notch image quality.

To be honest, I doubt most people really care about smart TV. I imagine most of the smart TVs currently in use are used only for basic TV features. Smart TV is mostly of benefit to marketing people looking for something to differentiate their product from someone else's. Features that can be included in a bullet list are easier to market than qualitative differences.
