French Riviera + Faroe Islands vs Greek Islands

Hello! We are planning a last week of August + early September 2026 honeymoon. Our options are either 12 days in the Greek islands, or doing 6 days French Riviera (staying in Nice), and 5 days in the Faroe Islands. Two very different trips and we are very familiar with the locations, truthfully we just can’t decide and would love to hear from people who have been to either!

Thank you in advance.
