This is like comparing two beautiful women. So many intangible factors apply. I have skippered in both places many times, and all I will tell you is that if you love sailing, perfect beaches, shallow snorkeling, beautiful small towns and goombay bars, do not miss the Abacos. Screw the tides and shallow waters - it is not that difficult to figure out. The BVIs are my favorite, but I still love making out with the Abacos.
