Depends. Is this just for one computer? Or to be shared amongst other computers?
If shared, I say then go with the Quicktime. Quicktime files have higher compatiblity rate from computer to computer. While .avi files, even when encoded right, can have instances in which the video file may not work across certain networks. Put this is more of a studio/school thing I learned. And besides, Quicktimes rarely are encoded incorrectly compared to .avi files.
If it just for yourself, but all means, go with the Xvid. That would just work perfectly.
