I would be curious to know how you prepare your salt and administer it to your system. I use strickly kent marine and have found it to be excellent and consistent. I switched from IO years ago and went with kent marine. been there ever since, so, lets dont bash a salt for the sake of bashing it. if something is wrong lets post the comparison and data to go with it. Now having said that, im sure some of the new salts are just as good and several may be better depending on the system. Every system is different and will sometimes react differently than others with the same salt. To get a balanced consistent buffer store, you can use Kent RO right to condition your Ro water for 24 hours before addition of the salt. Your salt must be added not too fast to the total water volume you intend to use, aireated and mixed for 24 to 72 hours, brought up to the same temperature as the system while mixing and aireating. Now if you all did that, and you had problems with the salt, id be interested to know. just my thoughts on the matter. ( some systems need to add Kalc and some need a calcium reactor depending on the coral/ load. this needs to be considered also). Bottom line is use the salt that gives you the results you are looking for and dont expect the same salt to always do as well for everyone. IMO
