I suspect it's largely a matter of whether or not you grew up with analog clocks or digital. If you're used to digital clocks, it's quite natural to give the exact time. With analog clocks - ones with a clock face - it's rather more natural to round off based on the position of the hands. At 5:45, the minute hand is on the left side, and it therefore closer to the next hour than the last one.
