According to the poll so far, when not sprinting, almost 70% don't use 6 beat kicks. However, what I see in the pools is different: most people use 6 beat (I didn't count their beats, but it's obvious more than 4 beats and definitely not 2 beats), whether sprinting or not.
It might depend on distance and intensity. I may use 6 beat kick for 800m as well if I swim in relaxed, easy manner. Sure that I don't kick as hard in that case.
