Question Itinerary Help: Malta + Sicily or Montenegro?

Hello, we're planning a 12-14 day trip and are torn between exploring Malta and Sicily or heading to Montenegro. Both options seem amazing, but we're struggling to decide. Malta and Sicily offer rich history and stunning Mediterranean views, while Montenegro is known for its breathtaking landscapes and charming coastal towns. Has anyone done a similar trip and can share insights on what to expect in terms of activities, ease of travel, and overall experience? Any advice on making this choice would be greatly appreciated!
