Web15 de nov. de 2016 · Both have their pros and cons, but ultimately bubble sort quickly becomes less efficient when it comes to sorting larger data sets (or ‘big data’). Where as, Merge Sort becomes more efficient as data sets grow. This makes more sense once you familiarize yourself with Big-O Notation and the concept of time complexity.
