I have done Tubbataha on one of the now defunct Expedition Fleet vessels but not the Atlantis Azores (though I saw them on the same reef a few times when I did it). I enjoyed diving Tubbataha because of the life along the walls, lush and alive. Lots of opportunities to encounter sharks, rays, and mantas depending on when you are there. Turtles are a common sight from the surface and underwater. Tubbataha Park is only open to divers and visitors between late Feb (I believe) and late June. I was there early March and there was not much action compared to reports from the April batch but it was still a fun trip with lots to see. A lot of shallow water areas have fields of smashed coral. Some due to fishing activities in the distant past, coral bleaching, and wave action. That's how atolls are made anyway, from coral rubble and sand being crunched up by marine life such as turtles and Parrot Fish, and wave action over the shallows. All diving are made from chase boats. I think the Atlantis Azores is the same way. All dives are wall dives sometimes with current and sometimes slack. I prefer diving with current because the large animals tend to be present when there is current. Also, currents bring out feeding fish from the reefs. Bring reef hooks. My hands got really tired holding on to rocks and fighting the current just to get a nice view of the animal action. I would do Tubbataha several times more during my lifetime. I do not think I will ever get tired of it.
