I have lived in Jakarta for 14 years, know a ton of divers, and do not know anyone who has been to the Togeans...or at least anyone who talks about it. Im sure the diving is solid, but in the world of the internet, Instagram, booking one's own travel, and sites like Scubaboard, the idea of undiscovered gems in places like Indonesia probably isn't very realistic. If people are not making effort to head to the Togeans, Bira, etc... there are reasons why. I think it is safe to assume the diving isn't worth the effort. That being said, the adventure and other experiences could quite possibly be amazing. I love my adopted country, and there is far more to see here than just diving. However, if you are planning the dive trip of a lifetime and want to see the best Indonesia has to offer underwater, there is a reason why Raja Ampat is what it is. I hope that helps.
