As someone already mentioned, AOW is a formal gate keeper course, e.g without it you can not dive in certain sites, can not take more advanced PADI courses. If I am not mistaken, you need to be AOW cerified to take Deep specialty.
In substance, PADI specialty courses are designed to make money from you but do not add many additional skills. I already took Deep, Night, Wreck, UW Naturalist, Drift, Search and recovery, Nitrox specialties. My view on them:
Nitrox - is a must if you want to dive with Nitrox. Nobody will give you Nitrox without certification.
Deep - it is worth as you can try yourself in deeper depth and see hoe you body reacta to gas narcosis. Also, officoaly opens sites up to 40 m depth. E.g. on liveaboard some sites were 32-34 m depth and LOB ooerator requires to have Deep specialty or equivalent to be allowed to dive there.
Search and recovery - fun course, got few additional skills, definitely worth try.
Other specialties - mainly waste of money
