people have had problems with the oceanic being abnormally high in calcium. I've been through 7 buckets and haven't had a problem, but you might want to find out if that has been corrected yet, or if you live in the same area as the people that have bought the unbalanced mix.
I've used many brands and to be honest with you haven't noticed much difference if any at all. Red Sea, Reef Crystals, Oceanic, IO, and i'm sure some more, i'd have to go look at my buckets, but back to the question to get the coralline growth, you just need a stable system and do regular water changes and normal maintenance and with time, you will have more than you want to deal with.
