Skype is so far the number 1 pick because it has a good balance between video and audio quality. However its fullscreen video quality could be better.
Video: The video is realtime at about 30 frames per second. It is not jumpy but it is somewhat blurry at times.
Audio: The audio is very loud. The audio quality is also very good with very little to no feedback.

Sightspeed has very good video quality at times. But the audio is not very good.
Video: Sightspeed has the best video out of the programs reviewed. The video is realtime at about 25 frames per second. Sometimes the video has a ghosting effect for a few seconds. The video also pauses sometimes.
Audio: The audio is just ok. Sometimes it is choppy. At other times the audio gets very loud and then it goes very soft a few seconds later. There is also some audio feedback.

ooVoo is a pretty nice video chat application where you can chat with more than one person at a time. However it does have some bugs.
Video: The video is realtime at about 30 frames per second. The video is very clear but it is not full screen capable. After clicking some maximize buttons it finally fills almost half the screen. It would be nice if it were bigger. Also, the video looks good, but about every 30 seconds there is alot of garbage pixels on the screen covering peoples faces, but the garbage disappeared after about 5 to 10 seconds.
Audio: The audio is very clear. It doesn't sound robotic. However, the audio is very quiet. I would give the audio a better rating, but it needs to be louder.
