Me too, um, did I say manga, I meant anime, yeah, anime! *nervous chuckle*
Actually I like both for their different reasons. Firstly, there was waaaaaaaaay more S x S stuff in the anime than the manga, at least to my understanding, and also Syaoran seemed funny, and he also collected cards in the anime whereas he didnt in the manga! Also, there were more cards meaning more COSTUMES! *cough* Okay, not all the time, but still. And I also thought Syaoran/Kero-chan/Touya was more hilarious in the anime than the manga
Manga wise, the Yukito/Sakura stuff was more indepth to me, not to mention the ending was waaaaay cuter as well. To me, the message seemed like they were destined, ya know, like no matter where you are or how long it takes i'll still love you, type of message. XD The anime was sweet too, except I thought the ending for the movie annoyed me! Being the hardcore fan I am, I wanted to know what happens next! But the ending didn't seem that bad, I mean, it was cute, but I really did want to see if Syaoran would actually catch her >.< *nerdy* Also, they explain some other things that are not mention in the manga, like, how Fujitaka, Sakura's dad, is the other half of Clow Reed, that Kaho and Eriol really do love each other, and Rika-san and Terada-sensei are 'engaged'. <---highlight to read spoilers.
All in all, the manga and anime both rock, since they both have their own special traits. But looking at my erm, list, I think I perfer the anime more, especially since it is well ANIMATED! *cough*
Wow, looong, post there. *whistles*
