Bill Wilcox is one of three people who are acknowledged as helping to put together the Hook-N-Line map of Ray Roberts. It has approximately 130 points of interest and their GPS coordinates. For fishing spots, it tells what type of fish you're likely to find there and during what months.
I have a Martin's map for another lake and it is definitely very detailed with tons of good info. However, the color scheme and fonts used are harder for these old eyes to read. There is a GPS grid that you have to use to figure out the coordinates of a spot. Overall, a lot of the map includes advertisements that limit the size of the actual lake portion of the map.
I don't think that there is any one best map since they all have strong points. Make the Tackle Monkey happy and get a couple and really dissect the lake.
