Hi Cindy,
Thanks for your pm to me.
Some of the corals in your pictures look nice but I assure you that Bali and Bunaken have similar if not better quality.
That is what make me wondering why you are confident to make such a strong remarks.
Anyway, what make a diver choose the destination is not about the corals only, one of the main reasons is the creature they can find, specialty and experience.
Bunaken has very pristine and beautiful wall, also good macro in the shallow reef, nearby there are also best muck diving in the world, same with Bali.
Bali has very diverse diving, from wall to wreck and muck.
One poster asked you whether there are certain fish you can find there, which is a good/strong point that weight into decision of whether to visit a place. Example, divers visit Bunaken/Bali to see frogfish, ghostpipefish, flamboyan cuttlefish, boxer crab, mola-mola, rhinopias. bobbit worm, pygmy seahorse and many more things.
It's true that each diving destinations have their own beauty and specific related experience, but
there are not many places in the world that can compare to these two, imho. Compare is hardly. Surpass, I really doubt it.
I'm in close contact with some divers who have gone to the three places you compare, there is not a single word of comparison and Batam has never came out as something to mention.
Don't get me wrong, I actually see good spirit in your enthutiasm.
Just be careful with the strong remarks that most people here might find it questionable.
I also agree that beside asking us to give it a try, you probably can go Bali and Bunaken to see why I find it skeptical to compare.
Cheers,
