I have been to Belize (AC) and Cozumel each two times. For reference I have also been to Bonaire 3X, Curaçao, Akumal, Dominica, Grand Cayman, and Saba. Everyone has their favorites and different things appeal to different people. I have more interest in going back to Belize than Cozumel. You will see more fish in Cozumel than Belize but Coz has mostly smaller fish. In Belize you will see more eagle rays, stingrays, nurse sharks and turtles. Drift diving in Coz can be fun but depending on how strong the current is it can be frustrating for a photographer. There are definitely quality dive ops in Belize. I find San Pedro a more interesting town than Coz and it definitely has better restaurants. Fido's is my favorite tropical bar/restaurant. Plus as others have said topside adventure activities on mainland Belize are fantastic. But Belize will be more costly than Coz.
