Blacks & Whites
The Panasonic has the edge here; the blacks were much deeper and the contrast range between the black and the white was much whiter. But the Vizio has much brighter whites, which could be a very significant point if you watch TV in daylight or want to use the display as an office noticeboard.

Motion
Both displays also had decent performance when it came to motion; we saw smooth motion from both displays. However, we saw more problems with the panasonic; some objects had a faint trail behind them (particularly green objects), and sharp edges on fast-moving objects became broken and jagged as they moved across the screen. The Vizio did have similar issues, but they were significantly less pronounced.

Viewing Effects
There is no competition when it comes to viewing angle: the Panasonic is the clear winner. It managed to mentain a high contrast ratio all the way out to 80 degrees off axis, while the Vizio could only manage about 17 degrees.

Connectivity
The Vizio has a wider range and number of ports, including more HDMI ports and a VGA port for connecting a computer to the display. The Panasonic has only three HDMI ports, and no VGA port, which means you would need to use a DVI to HDMI adapter to connect a computer with a DVI port, and you could not connect a computer with just a VGA output port.

Other Comparisons
The other ace the Vizio has up its sleeve is the support for playing back photos, music and videos from a USB drive. However, given that the features to manage these files are rather minimal, it is not much of an ace. More of a jack of clubs that is suitable for showing holiday snaps.
