Both technologies have their pros and cons so it depends on where you want to compromise. 120Hz, 240Hz, etc are all multiples of 60Hz and every tv mfr handles that motion interpolation a little differently. Some are better at it than others. A high Hz rating doesn't guarantee absolutely smooth performance on fast action scenes (eg. sports). Panasonic does indeed make a fine plasma (they bought the Kuro patents from Pioneer) but banding can be an issue on some of their panels.
