You can't use the increment operator at all on Strings.  So there's no 
"better" comparison between them, except for the trivial "one compiles, the 
other doesn't."

"The result of the postfix expression must be a variable of a type that is 
convertible (§5.1.8) to a numeric type, or a compile-time error occurs."
- JLS, §15.14.2

Nope.
