I give both 10/10. 
I don't give many movies 10/10s outside of my top ten few movies lol. But I'd give Toy Story a 10/10.
I watched Lion King again a few months ago and I'd say 10/10. Now I need to see Beauty and the Beast again; I loved it as a kid and I'm sure it holds up, but I need to see it again.
Hmm in terms of animation (no order)
Pinocchio 10/10 (scared the SHIT out of me when I was a kid)
Nightmare Before Christmas 10/10 (I've probably seen this movie more than any other outside of Forrest Gump)
Lion King 10/10 (some complain about the music...but it's perfectly balanced and amazing)
Princess Mononoke 10/10 (like EBERT said, it's the Star Wars of animation

)
Castle in the Sky 10/10 (one of the most beautiful movies I've ever experienced, on every level)
I'm missing other pefect ones too, just can't think of any
