Personally, I think both of those products are garbage and do nothing more than pollute your water quality. There is no telling how the product has been shipped, what temperatures it was exposed to and how long it's been sitting on a stores shelve. I'd much rather feed my corals PE Mysis, Reef Nutrtion Oyster Feast and Reef Nutrtion Roti Feast. They also make a good Phyto Feast. Of course, they're more expensive than their unrefrigerated competitors, but sometimes, you get what you pay for.
