Programming is in my opinion not just about data structures and algorithms. It is also about designing abstractions that capture the domain you're working in well, whether it be by designing classes in an OOP language, or data types and functions in a functional language. It's not just about what a program does and how quickly it does it. What matters at least as much is how easy it is to understand, modify and extend. Of course, that isn't necessarily language-dependent either, but I think some languages make it easier for you to design nice abstractions. For example, C can make it more difficult to write nice abstractions since it forces you to worry about memory allocation and memory safety, and doesn't really offer facilities for generics.
