I have the NV chart kits which I purchased down island. Not sure how they compare to other chart kits. But I found them to be great.
3 kits cover the entire region, and most important for guidance each has a "Harbour and Anchorage Pilot" booklet with excellent anchorage and harbor guidance routes/waypoints etc.
I also have Doziers Bahamas Guide 2010 which has lots of general info but no piloting - no routes into harbours/anchorages. So is completely useless I would recommend not buying
I returned to Nassau
last week with new Raymarine
E120 - the included charts do not have as complete detail as the paper charts - so often returned to paper. (Need to upgrade electronic charts - bastards)
