Optimized sort vs Quickselect

With the implementation of Quickselect done yesterday, now comes the question: is it quicker to use an optimized algorithm to sort the whole list then find the i-th element instead?

As expected, it depends on the list size. For short list (maybe < 10 items), optimized sort is faster. But otherwise Quickselect is faster because it only sort part of the list.
