good workflow for comparing multiple videoclips in realtime and picking one?

Hey,
I have a project with an audio track, and 3 video tracks, all video tracks having either a long clip or multiple shorter ones (sometimes with gaps in between), all are of course in sync with the audio track (and hence with each other). The video clips are basically the same thing being filmed, but from different angles

What I'm trying to do is compose a video, using the best clips from different angles. But I haven't found a good workflow to do this.
Maybe I'm missing something, but the default way of having 1 project preview and separate clip previews is not very convenient. As, the project is playing, I'ld like to see all the video tracks playing at the same time (as well as the project video stream), then I could more easily see which clip I want to use at each point.

thanks,
Dieter
