If I wanted to go high end in close proximity to restaurants, I would go with Cozumel Palace and dive with Living Underwater. If I wanted to be able to add shore diving to my boat dives, I would go with Blue Angel and dive with their on-site op (bring a lock for your locker). The on-site restaurant is pretty good and there are many, many more in town in a 10-15 minute walk. (And it's very safe to walk in Cozumel.)
I would NOT stay at one of the southern resorts because they are just too far from town and the taxi rides are killers. If you want to get away from everything, I guess they would be an OK choice. The Presidente is a bit further south of the two places I have mentioned and is a $8-10 taxi ride to town each way. Most all of the dive operators dock their boats in the little harbour right next door to it so, as others have said, you have scads of ops to choose from at your doorstop.
As others have said, people who dive in Cozumel a lot seldom book the on site dive op; rather they mix and match finding an op that meets their particular needs and wants.
