Another & AIR TV are still in my high top twenty, and I still really like Black Cat due to nostalgic value. =)

I want to keep liking CLANNAD due to the fact that it's incredibly nostalgic for me, as well, but the more I re-watch the series, the more I'm annoyed by it rather than genuinely enjoying it, despite if I continue to reminisce.

Air and Another :)

The other three I've been meaning to watch, but I like Black Cat ^-^

i liked clannad after story a lot, but i didnt really enjoy air or another and i havent seen black cat

and Another.
