Sailing
The BVI wins for pure sailing. The Sir Francis Drake Channel — the sheltered waterway running east-west between the island chain — is one of the world's great day-sailing venues. Sixty islands provide variety for a week-long itinerary; passages are typically 10–20nm; and the trade winds deliver consistent 15–20 knot sailing without being overpowering. The BVI was designed by geography for sailors.
The USVI has excellent sailing but fewer islands and less variety. St Thomas to St John is a lovely day sail; St Thomas to St Croix (40nm south) is a proper offshore passage. The best USVI sailing combines the main islands with a crossing to the BVI for the second half of the charter.
Scenery & highlights
BVI highlights: The Baths on Virgin Gorda (extraordinary granite boulders and natural pools), Norman Island (inspiration for Treasure Island), the Soggy Dollar Bar on Jost Van Dyke (birthplace of the Painkiller), and Anegada's reef and lobster.
USVI highlights: St John's Virgin Islands National Park (one of the Caribbean's finest beaches and snorkeling at Trunk Bay), Buck Island Reef National Monument off St Croix (outstanding snorkel trail), and Charlotte Amalie's duty-free shopping.

Practical differences
The single biggest practical difference: US citizens don't need a passport for the USVI. For American charter sailors, the USVI's status as a US territory means no customs, no passport requirement, familiar standards, and direct flights from most US cities. This is a significant convenience advantage for multi-generational groups or anyone travelling with children.
The BVI requires a passport and a Cruising Permit ($75 for vessels under 35ft, more for larger boats). If you want to combine both, you clear customs at West End or Road Town when crossing from USVI to BVI.
The verdict
Choose BVI if: you want the best pure sailing itinerary, your group holds non-US passports, you want maximum island variety, or you've done the USVI before.
Choose USVI if: you're American and want the convenience of no passport/customs, you want to prioritize the national park beaches and snorkeling, your marina and provisioning standards need to be US-level, or you're doing a combined USVI+BVI charter.
