I've just noticed that Doom9 has published his annual codec comparison:
http://www.doom9.org/codecs-final-105-1.htm#intro
The new winner according to Doom9 is x264 (Ateme/Nero AVC encoder was the previous one, and his now second). Additional but interesting info: in the next weeks a new branch of XviD will become public: XviD AVC.
The battle is just beginning!
