I have read a lot of manga and watch a lot of anime only to be disapointed when it ends.

What anime have guys been dissapointed by? it seem like towards the end a lot of them are rushed out.
The latest example has to be Tenjou Tenge wich was horrible at the end.
Now I like that some anime changes things a bit from manga but I think most of us like to see what we read in real motion.

Now what I want to know is wich manga do you think is better then anime and wich anime do you think is better than the manga.
For example:
I happend to like Chobits the anime better than the manga. The manga gets to romantic at times while the anime is funnier.
On the other hand I like GTO the manga better then the anime because it has a lot more detail and has more stuff happening and they also rushed the ending on the anime.
