Until you have to clean them, cartridges are easier. With sand, to clean you turn a valve, let the pump run for a couple of minutes while sipping a drink, shut the pump off, turn a valve, let the pump run a minute or so while sipping a drink, shut the pump off, turn a valve, turn the pump on and go swimming. IMO, cartridges are the hardest type of filter to use and sand the easiest.
