The thing about resort & dive shop trip reports/reviews is that unless you know something about the person's previous travels, tastes, dive experience, etc., and it's similar to your own, you should take it all with a grain of salt.
If all you do for diver trips is one a year and it's always an AI resort/on-site dive shop package deal then any resort/dive combo you get that way will seem good. The beauty of a dive trip to Cozumel is that you aren't limited to using the onsite shops. There's a shop in Cozumel to suit just about every diver's "must have" list.
A lot of divers that stay at the AIs on the south end of the island book with one shop for their morning dives and then use the on-site for afternoon or night dives a few times during their stay. You just have to decide which days you want to do that so you take your gear off the boat in the morning as many dive ops will rinse and store it for you as part of their service.
