Snorkeling-St Kitts or Antigua

[Wayfairers]

We have two new Caribbean ports on a 2015 cruise....St Kitts and Antigua. We've snorkeled throughout the Caribbean including BVI, USVI, Barbados, Jamaica, Aruba, well you get the idea. Am I correct to assume snorkeling in St. Kitts and Antigua is similar to the other islands? Which one of these two is better?

I haven't snorkeled in Antigua, so can't give a comparison. However, we were in St. Kitts 11/2013 and snorkeled off the beach at the Marriott. It was pretty decent for Caribbean snorkeling. Saw our first lion fish.
