I can help, but my memory is kinda foggy since I read the book last year. (And also because the movie takes up most of my memory.)
Pros:
-can see colors
-exclusive access to a certain place (can't remember exactly where)
Cons:
-know hatred, abuse, sadness, etc
-being different from the other kids
-know the "real" world
And that's pretty much it. I try to answer questions I know at least a little bit about. :)
