Could somebody please sum up the advantage of a third color format being used in AviSynth?

Don't know about others but my own reasons are fairly simple.
1) Color conversions are potentially lossy, and slow.
2) Most of my video input comes from DVD's or HDTV and both of those are already in YV12 format.
3) Most of my video output goes to MPEG2 or MPEG4 (Divx or Xvid) also in YV12 format.
4) Some algorithms run faster or are easier to write when working with planar 4:2:0 data.
