My preferred coding style is C-style with some modern conveniences. As I studied CS in college I learned which kind of code runs really fast: for-loop algorithms on contiguous blocks of memory, and since I was inspired to code video games I was able to build a lot of fast and robust features like this.
Arrays are my favorite code design pattern because they are pretty much universal to all languages, indices can be used like pointers, and you can get a lot done with a very small amount of code.
