Aqualife is one of the best-equipped dive shops on Boracay. Their rental stock is of Mares products never older then a year. Aqualife is one of the few shops that use a speedboat to bring you to the dive sites, so it never takes longer then 10 minutes to get you there. I have taken a lot of dives with them. They have friendly staff, good instructors, and dive masters who know where to find the things you like to see.
I can also recommend the day trip to Maniguin Island, 1 hour by speedboat from Boracay. It’s a bit expensive, but you get three beautiful dives and breakfast and lunch between the dives. (They leave at 6am in the morning, hence the breakfast). Because Maniguin Island is 1 hour away from Boracay (4 hours from Banca), you will find unspoiled coral, lots of fish, and often even sharks.
