2006 version is much better than 2002 version
imo, the 2006 version of kanon is much better on story than the 2002 version, because:
1. it is created by kyoto animation w/c they'd also created The Air before in 2005 w/c on that series it was the same people who created kanon.
2. on 2006 version, the number of episodes is 24 unlike the 2002 version w/c only contains 13 episodes and 1 OVA.
3. the 2006 version might get a license in North America soon but not the 2002 version.
