This is a topic of another thread on this forum. A lot of it comes down to taste and how you feel about aquacultured vs colllected live rock
Personally I want to do a tank in Caribbean Rock someday and turn it into a completely Caribbean biotope with gorgonians, ricordia and sea mats. The only wat to get any Carribean hard corals is to get those that naturally grow on the aquacultured rock.
Many people do not like the rock because much of the life on it dies, longterm, and it is much more dense than some of the pacific rocks.
If you prefer pacific aquacultured rock you can always go with Walt Smith.
