I'm assuming you're talking about Higurashi. It always seems that when I watch a version of a series first (anime or Manga), that is always the one I like the best. So, I decided to just do both at the same time, which is why I bought 4 volumes of the Higurashi manga earlier this week (The Curse Killing Arc and the Time Killing Arc). I have to agree that the manga versions are better, though.
And yeah, it was ep. 9 of Kanon that made me cry. And about 5 times during Elfen Lied for me as well.
Oh, and I have the first of the Higurashi sound novels on my laptop. =)
