Gotta love Studio Ghibli.  
 
-My top 5-
1. Castle of Cagliostro
2. Whisper of the Heart
3. Porco Rosso
4. Grave of the Fireflies
5. Totoro
I have to say, Earthsea and Ponyo were not up to the usual standards IMO.
Wow interesting taste 

 I was shocked for a moment and though I had somehow missed a Ghibli movie when I saw 
Castle of Cagliostro was your number one... Reading up on it I realise now. My top 5 go something like this:
1: Princess Mononoke
2: Nausicaä of the Valley of the Wind
3: Ponyo (dayo) on the Cliff by the Sea
4: Laputa: Castle in the Sky
5: Whisper of the Heart
Though really it's so difficult to put them in such a short list.. Pretty much all of them are my favourite.. It's the only animation that I like (other than Ghost in a Shell) 

 I think Ponyo is an absolutely beautiful movie. I watched it three nights in a row and I have never done that before.. Makes me so happy and the Japanese is really basic as well..  SO I can understand a lot
