@PatWThe vast majority of my diving is in the Caribbean and the adjacent Atlantic, I have dove Fiji and Sulawesi. And both of those were nice. But after the hype, I expected more.
The fish in the places I went tended to be small and rather shy.
I think the angels of the Caribbean: Queen, French, Grey and Rock Beauty, stack up favorably against anything I saw in the Pacific and Coral Triangle. The Nassau groupers stack up well against anything. And spotted eagle rays are way cool. The gorgonians of the Caribbean are great in variety and form and the Caribbean has many lovely sponges.
The odd thing was that most of the coral colonies I saw were pretty small, there were some big ones and some REALLY big ones. But the Caribbean has some really nice hard corals if you can find some healthy ones.
Now, Indonesia had some really cool flatworms that were big (well 1” +), and Pygmy seahorses, and a bunch of nudibranchs … all good fun.
In the Caribbean, I am used to taking photos of the butterfly fish. And when you use a strobe (I do 100% of the time) , the scales reflect the light and I have to be careful to not overexpose. But nail the strobe setting and the effect is great, I did not have that happen with Indopacific butterflies and that was a disappointment.
Was the diving good? Sure. Was it worth it? For me it was. I suppose anything can be overhyped.
Sulawesi and Fiji are nice diving destinations, but do not represent the explosion of life available underwater in places like R4.
The Caribbean has ~65 varieties of coral, the Coral Triangle (R4 being close to the center) has over 600 varieties of coral. Bluntly, the Caribbean is like diving in a bathtub - it's warm, it's nice, but it's very limited.
Speciation (as part of evolution) is visible in different places through different species. Angelfish are a good example. You mention you like the angels found in the Carribean. The most commonly found ones are the Queen, Blue, French, Gray, and the Rock Beauty. In the Coral Triangle that number is 10x, and they are still discovering local or regional variations that may be new species. As an example, for me, the juvenile emperor angelfish is easily more striking than any variety in the Carribean.
