I spend a lot of time in Antigua and have come to like the island. Cruising there is quite different from the BVI.
There are fewer boats in the anchorages than in the BVI as there is less charter activity and many of the anchorages have no bars/restaurants on the shore. The island is bigger and more populous than the BVI and in recent years they've become friendlier and more service oriented than they used to be (well, apart from the customs and immigration folks).
Anchorages such as Green Island are wonderful. https://www.sv-zanshin.com/blogpages/2016/blog2016-05-05.php
