Bora Bora, Tahaa/Raiatea offer pretty "decent" dive sites. But the "Tuamotus" islands are complete different dimensions.
Ranguiroa is very famous and their main pass is spectacular.
we used the 6 passengesr club and liked the DM with a huge compass tatoo on his back.
Tikeau is less known but also has a few decent sites
Fakarava is my favorite. As long as you use this club:
club
and not the other morons.
here is a quick video. You have thousands of them (to dream before going)

(the manta are from inside lagoon of Bora Bora)
As mentioned above. It's expensive, especially with the current $ value.
Not only the diving, but also the hotel, or "pensions", the food, the flights (get a pass if you plan to visit multiple islands).
Note: it's not easy to get this air Tahiti island pass, and I'm not sure some US travel agency can do it.
It's a great high-end vacations place and really, the diving is super cool !!
