Base maps are only a basic map

Either of the mapping programs should provide you with maps that have greater details than the BASEMAP.
I believe that In order to avoid sticker shock on the price of a new GPS unit that the manufacturers include a basic mapping program. Yes, it is enough to get you out on the water, but it usually does not show all of the small cuts and bayous that make up the Louisiana coastal marshes.
I suggest that you go to a stocking Lowrance dealer and ask to see the mapping programs you mentioned in a GPS unit.
Pick out an area you know and zoom in to your fishing spots..
That will give you an actual view of what you will have in your unit..
Pick the one that best suits your needs.
Be sure to get it in the proper type of memory card for your unit.
