You need to define precisely what you mean by "best" to you personally.
As far as laying, a dusting of ground peat is good, never hurts, can only help, not messing since there's not much, but as mentioned, not needed if you chose ADA AS. ADA can be messy for some folks, not the best stuff for folks that uproot often. Loaded with ferts. you can add about 5 grams of osmocoat per sq ft also if you so chose.
Sand, SMS, cheap etc, no nutrients.............so you do not get that benefit.
Mineralized soils/clays: cheap, but a lot of labor/work.
I like to use all the methods to make life easy. So water column dosing is easy and good, as is sediment ferts. Using both together makes life that much more simple, easy. You get more out of each source and have more flexibility, longer life from the sediment and less worry about dosing enough in the water column.
Really depends on the rate of growth and what type of work/labor you are interested in. Then there are aesthetcis, which rank pretty high with sediments.
