Typically, pre-defined functions are better, if they exist. They usually are optimized to operate in the least amount of time, no matter what the input (they optimize based on input type and size). Really, the only reason you should user-define something is if the functionality of the pre-defined code does not meet some certain requirement that you have. For example, there may be a search function that has been pre-defined and returns a boolean, but you need to know the index of the found item.
