Now for sand, whether play sand or pool filter sand, make sure you rinse well - and I'm talking bucket and hose rinsing outside (cool beverage optional). You really want to rinse it really, really well to remove the 'fines' (dust like particles) lest you'll be fighting cloudy water after it's in the tank.
As for cleaning, unless heavily planted, fine gravel may require the occasional gravel siphon cleaning. For sand, it's merely a hover over method as needed. Also for sand, some feel it needs to be stirred. I think if you have some Malasian Trumpet Snails to stir the upper inch (or stir the upper inch during weekly water changes) your fine. Again, moot if the tank is heavily planted. And don't worry about anaerobic regions down under as they are inevitable and not the concern some seem to think. (It's actually stirring detritus deep into anaerobic regions that can present a problem.)
So there you go...sand or fine gravel. Both work well. In some ways, sand may have a slight edge.
I'd even go as far as saying, you may not have to clean the pool filter sand. I didnt, and my tank never clouded up. If you are precautious one, then go for it. But be sure to use the plate method in filling up your tank, so the water pressure doesnt stir the sand around (which will cause cloudy water). With play sand tho, there is no getting around it, you will have to rinse, and rinsing play sand is tedious and a pain.
