The English language version of Final Fantsy VII: Advent Children (FFVII: AC) was released on the 25th in North America. Had you get yourself a copy yet?

I don’t really care about what language the character are talking. Just wathcing at the CG would probably amaze anyone. If you love FF:The Spirit Within, I bet you’ll love this one as well (Did I hear anyone say “NO”?). Not a FF fan? Me neither. But the first time I watched it, am I hooked!
Final Fantasy VII - Advent Children (UMD Mini for PSP)

The only contender that I would think of will be “Apple Seed”. It’s a surprise that most people/anime fans/CG fans aren’t aware of this great film. If you look around, you will find that it got the best CG in 2004 (or something similar).

So, my conclusion: Watch both of them! Both of them are great and I wouldn’t want to miss out either one.
