I think it depends on what you like and don't like.

We really enjoyed St. Barths. Gustavia was quite nice with lots of high-end shopping and restaurant options as well as some moderate choices too. It was trendy and busy - even in the summer. Around the corner from Gustavia was Colombier anchorage. A bay with a very nice sandy beach and some good hiking up on the hills around it. The beach was somewhat busy during the day but cleared out at night. Plenty of mooring balls, but if I remember correctly I think that anchoring is not allowed there (though I could be wrong). We had a BBQ dinner with some quality steaks, potatoes and veggies that we bought earlier in Gustavia and a nice bottle of French wine. St. Barths is a very French island.

We stopped at Nevis & St. Kitts and didn't find them overly exciting. That was probably at least partly because we were hunting down a new water pump and making repairs at that time though. Enjoyed a peaceful evening anchored at Ballast Bay at St. Kitts. Had a very good but very expensive meal at the Four Seasons on Nevis, another good dinner (and more affordable) up on the Hillside in Basseterre. I think if we would have gotten inland and away form the boat we may have enjoyed Nevis & St. Kitts more.

If you have the time and can make it far enough down, Barbuda has an absolutely amazing beach and Antigua is a very interesting island. The frigate bird tour on Barbuda is worth it and other than that, did I mention how great the beach is? On Antigua we enjoyed English Harbour (where we had a massive squall/lightning storm come through) and Nonsuch Bay was nice as well. Several places to anchor around the bay and there are a few mooring balls behind Green Island. You would have a few long sails to make it to Antigua/Barbuds and would need the winds and swell to cooperate, but we personally enjoyed those islands more than Nevis/St. Kitts. Just my opinion.
