I have been using TM Classic for 1+ year now.  Bought a 50g bag of IC to try out since its much cheaper based on list price.  I'm on my 2nd WC with IC and noticed i need ~30% more IC compared to TM to get to 1.025 salinity.  The first WC, i didn't think too much of it.  With the 2nd WC, its clear that i  need approximately  4 cups of salt to 9g of water ration for IC , versus  ~3 cups/9g ratio for TM.
Taking that into consideration, the actual cost is different is less significant. I probably will stick to TM since it works well for me.
I cannot comment if one brand is better than the other. I think this is a very subjective topic and there is no right answer. Just sharing my observation.
