The problem with all the streaming video tools I've used is that the quality drops dramatically. They produce something viewable in small screen but make it full screen and it is like a John Logie Baird original. This is especially true if there is a lot of movement. In all cases I'm choosing to broadcast the highest quality of video the application allows.
So far I like the facilities of LiveCliq best but I think it gives lower quality than Bambuser. Bambuser however fails completely if it can't stream immediately.
Looking also at FlixWagon. Not sure the video quality is any better than LiveCliq. It does however automatically cache and upload later when it has to.
Nothing comes close to the near live option. Record as a video clip and then upload to YouTube.
Having said that LiveCliq is great if you just want a bit of a video diary.
