I don't think there's any real advantage to one over the other, it depends on what you like or think is easy.
Personally, I use table sugar (about 4.5 oz) so I don't have to buy anything special. Just bring a cup or two of water to a boil and mix it in. Let it sit for a minute, then put it into the bottom of the bottling bucket and rack on top of it. If you put your hose all the way to the bottom. You won't get any aeration.
