And then there's 4K TVs... ;)
1080p is the only way to go if you want to be fully compatible with HD TVs and videos.
As for 120 Hz TVs, modern LCD TVs don't suffer from ghosting and motion blur as much as they used to, forcing many users toward more expensive plasma TVs.
The "ghosting" effect means that when the current that powers all the LED diodes to display one image is cut, the image still persists on screen for microseconds before the LCD diodes are powered on for the next frame.
In any case, HD TV is shot with HD digital cameras only at 60 frames per second (60 hertz), and the same frame rate applies to Blu-ray discs.
Older movies shot on film were actually shot at a lower 24 fps and then upconverted to 30fps, 60fps for HD playback, so even with "only" 60Hz TVs, all you get is not extra crisp definition at high speed, but extrapolation or rather interpolation.
The difference between 60 and 120 Hz is usually hardly noticeable, except for high speed scenes as SWKS mentioned, but it seems to be the new normal for TVs, so it would be a safe investment if the extra cost is not too expensive or if you value high speed action. But high speed benefits much more from being shot with high speed cameras than being played on 120 MHz TVs.
