I would imagine that this is the better product for adding the good bacteria to a tank. Some products are not refrigerated and just sit on a shelf in stores until they are purchased. I would think that refrigeration would sort of put the bacteria in a suspended animation state, or at least slow them down so that they can survive a long time in the package. Some of the products out there get pretty bad reviews and apparently do nothing at all. Some get some good reviews. I haven't followed which ones are the good and which are the bad ones and don't remember where I saw the reviews.
If you have an established tank, it's not a real problem with water changes since most of the bacteria are on surfaces like the gravel, bio-media, the glass tank itself, filter surfaces, filter floss, etc. As long as they don't dry out or sit too long in a filter without water flow they'll still be there when you add the water back.
But this could be a great way to speed up the cycling of a new tank. With plants taking care of the ammonia right off the bat, that bacteria culture would help get things established quickly, possibly fast enough that you wouldn't need to do as many water changes in the beginning. And the name on the package looks like one that can be trusted.
