Wow, run-on sentences. Gotta take a breather....
Anyway, I personally like Fruits Baskets MUCH more than Karekano.
I probably didn't like Karekano because I don't like the characters that much, and after a while their problems didn't really matter to me. I loved the first few episodes, when they were falling in love. After that, it bored me and I didn't watch it anymore.
Fruits Baskets definitely has many more hot bishie characters, but its not so much a mushy love story as about friendship. And I liked Tohru more than Arima.
Karekano wasn't bad, just not my thing. Its just personal preference really. They're both pretty good series.
Come to think of it, it never occured to me that were that similar, but I guess they are...
