Hi:
I've done both. Definitely an either/or situation timewise.
My preference is Anguilla. Beautiful uncrowded beaches, great snorkelling on good days (Crocus Bay), smoother ride (usually, but not always), friendlier people if you drop the hook and go ashore....Dune Preserve, Shoal Bay East (or west).....lots of other choices. Your captain should know (or, are you the captain?).
A great day if you luck into favourable conditions, and we usually do (15+ trips)
Have Fun!!!!!
