@Zhnujm:
I think it's pretty hard to judge compression results of a whole movie if the quality between two outputs is not too far part.
Even if you make screnshots and compare them side by side, it's sometimes hard to tell which is better since one lacks here and the other there. Furthermore, this will usually be a comparison of I-frames which doesn't tell about the P-frames inbetween. It won't tell about correct motion vectors either or about the distribution of bitrate above a longer time.

Surely it's also a question of personal preferences. Current transcoders tend to cause macro blocking. Reencoding using CCE (or whatever) tends to cause blurriness and edge artifacts (noise around hard edges).
