Once you move outside of academia and thesis, it isn't the algorithm, but the implementation that is important. A mergesort programmed badly can be much slower than a bubble sort done well.

And once you recognise that in the real world, implementation is king, any kind of disk based sort is glacial compared to a memory-based hash.

It isn't the similarities, but the differences that are important.

A stately home and a plane both have wings, windows and seats, but the differences outweigh those similarities for most practical considerations.
