I have dived quite a few times in Bunaken, Gangga (Bangka) and Lembeh.
In the last few years I have mostly split my time between Gangga Island and Kasawari Resort Lembeh as I've found the variety of diving in the Bangka area to be much better than in the Bunaken area. I still visit Bunaken, but this is now a "day trip" from Gangga instead of staying there.
Over the last few years I have also seen more and more Lembeh type critters in the Bangka area.
