It all boil down to your budget. Based on like and rating, the resort I've been too are;
1. Bora Bora Lagoon Resort, Tahiti (be prepare to burn both hole in your pocket if not more)
2. Paradise Cove, Mauritius (Nice land and sea activities, love especially the deep sea fishing)
3. Hakuraa Club, Maldives (Small Atoll, all you need is 20 mins to cover the circumference of the atoll)
Not to mention others that I dream to be there are;
1. Turtle Island Resort, Fiji
2. Nika Resort, Maldives
3. Cocoa Island Resort, Maldives
4. Palm Beach Resort, Maldives
My suggestion is leave Bora Bora Lagoon Resort out and visit the other I've visited. As once you hit Tahiti, you'll felt that the rest pale in comparison.
