I can't answer your question as to what is the best web cam but I can tell you that your internet connection as well as the connection on the other end and all conections in between need to be good in oder to keep a smooth flowing web video conference. The biggest bottleneck with online video is not likely to be the camera itself but the speed of the connections. If either you or the person on the other end are on a dial up connection then the odds are very good that the picture will be choppy. Generally you must set the quality of the video (i.e. frames per second as well as picture quality) to match your connection speed. Real time video takes up a lot of bandwidth and if you try to send or recieve too high of quality/speed then your connection simply will not be able to keep up. Hopefully someone here can give you a bit more info on camera quaility.
