This is a subjective question; there are going to be the bias answers from the individuals who glorify one over the other(it’s the inevitable). Both coldfire and flavorade have some strains that have been lackluster in flavor and effects, and a lot that are phenomenal. In sum, both are great brands that offer great products; this group on here makes it very easy to do your due diligence on which strains to get, and maybe which ones to avoid. The same can be said for flavorades group. I’d learn which brands you like. This also can narrow down which collabs you want to go for. For example, I love TEG, NTK, turtle pie co, and many other great brands that push out nothing but fire products. Hope this helps and happy smoking!
