I can only give you the CCview perspective but had a quick look at Reef House and it looks interesting as well. I traveled solo to CCview on a 10-day trip and found it extremely easy to meet and mingle with the other divers as nearly everyone comes with the same mindset. They also team you up with the same boat/captain/DM/fellow-divers so they quickly become "family". If you are an experienced diver, as you clearly are, then you also have great freedom to dive solo on the house reef and roam around the dive group on guided dives. I find that important to get my images, especially macro.
I am a "house reef" guy. Making two house reef dives a day is nirvana for me and I've made up to 5 house reef dives a day on occasion. So my opinion may not reflect the general diver but if you want to do a lot of house reef diving in the Caribbean I suggest you do it at CCview. Even compared to my diving on Bari reef in Bonaire, supposedly the most species-rich reef in the Caribbean, I would still go for CCview. From the beach you have access to two fringe reef wall dives, a nice shallow fringe reef plateau on each with mixed coral ridges and sandy valleys, a sandy chute between the two reefs, a small wreck and, if you are so inclined, a backside where the open ocean meets a mangrove lagoon. Getting in/out is as easy as it can get and buoys&chain help you to find the exit and the second reef although it isn't hard to start with. When I was there we were dropped of on the far end of Newman's wall after the morning boat dive and on the far end of CCview wall after the after-lunch boat dive. Because you start at the far end you can cover a lot of reef and don't have to swim out and back along the same stretch.
If this is for you depends on your preferences. I hope this helps to make up your mind.
I got the newer AW130 which is waterproof to 30m, so you can stick it in your pocket even during scuba diving. I took it few meters below 30m and it was just fine. I like it to get GPS coordinates for a reef mapping project and it turned to be most valuable by giving it to my buddy who turned out to be excited in using it for video and doing a much better job at it than I would have done. No competition for a "real" camera, especially without lighting, but ok for documentation. I also typically come home with 2000+ fish images and not a single picture of my buddies or "surface time" because my camera never leaves the housing. Family seems to appreciate the latter much more than the former and the AW30 is a great stick-it-in-your-pocket camera.
Things are even a bit more complex. Using DNA sequences it became clear that the species D. albisella from Hawaii, D. strasburgi in the Marquesas match the DNA evidence. D. trimaculatus from the Red Sea and Zanzibar, and presumably the entire (Western) Indian Ocean , forms a distinct clade, more different than the Pacific D. trimaculatus is from the other three Eastern relatives. Some of the D. trimaculatus and D. auripinnis from the Pacific mix together on the phylogenetic tree so they really are very similar despite the different colouration.
One of the phylogeny papers also stated "On the other hand, D. auripinnis coloration patterns (yellow lower body and fins) may either be reflective of recent speciation with little genetic divergence (or lineage sorting), or due to ecological adaptation to turbid waters (Randall & Allen 1977)." They don't explain the turbid waters logic but often fish have a light belly to stand out less against the bright surface when seen from below. If the turbid waters are yellowish then perhaps a yellow colouration of the lower body works better. However, I've never seen noticeable yellow water colouration near reefs except for algal blooms in the shallow lagoons behind a fringe reef. I don't find it very convincing but it is my best guess at this point.
