My dream is to one day start a tank with TBS rock. The LFS's in my area has pitiful looking live rock. It looks more like dead rock that's just been sitting in saltwater. I've gotten some cherry fiji LR in the past but it seems hard to find good live rock now a days. If you want LIVE rock, I'd go with TBS. if you want rock with just coralline, some feather dusters and sponge, most rock would do. In my latest build, I used mostly dry rock and just seeded it with a few pieces of "œlive rock" from my LFS. It's also been getting seeded with stuff off snail shells and coral. I ordered a maricultured colony that has some cool sponge and other life under it. I also have several different types of feather duster spreading through the tank. It certainly takes longer, but it works and is cheaper and better than what my LFS has.
Again though, if money was no object and I didn't mind having to get rid of some pest crabs and stuff, I'd use TBS all the way. The rock I've seen from them is just incredible.
