Explorer charts are definitely the best. This subject has been discussed umpteen times on this forum. Use the search function.
Check out O- charts

Navionics charts are not recommended. Actually dangerous in some instances.
S-63 vector charts. Not recommended in this case. Useless and a waste of
money, except for a few
commercial harbors. The have nowhere near the coverage required by cruisers.
For Windows nv-charts is another candidate. While these charts are decent for the Bahamas, they are not quite up to Explorers standard.
