I think go according , what you try to grow or keep, only fish, LPS, Mix, SPS etc.
Personal , i like Tropic Marine Pro or ESV or Fritz , all great , Potassium is there , most of trace elements , etc. Low Alk. help to maintain Bacteria well, immunity of your tank . I use it most for SPS only.
I try Red Sea , but one have high Alk. the regular NOT sure if is great for SPS.
I will vote for Fritz in stand of Red Sea.
I did that I switched from the Red Sea coral pro to the blue bucket. I did it little by little adding salt from both buckets when making new fresh saltwater had no problems
