I'll have to say that the main similarities are the plot development and characters. Aizawa and Kohta. You'll understand once you watch both of them.

I'll have to say, Anohana was the saddest anime to date that I have watched, and Kanon 2006 came close to it. In both anime I was crying giant man tears and they both left that void of a good anime after it was done. The only difference is that Kanon 2006 rushes so much sad feelings that near the end I kind of felt that there was no lower I could go, and I couldn't cry anymore, but nonetheless both are really masterful works of art and I recommend both for must watch if you are into anime.

In consideration for the ecchi lovers out there =P. I recommend the To Love Ru series, although the first season isn't that great getting into the OVA episodes and later sequels, To Love Ru is a highly enjoyable anime with a unique addition of space aliens in a high school along with, well... the ecchi loaded scenes. Have fun ;)
